WineD3D translates to OpenGL. Assuming you're using Linux, it's as easy as running your programs in wine without DXVK.
Don't expect stellar performance though.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Yes, directx to opengl (included in WINE) was used exclusively for a very long time before dxvk and vk-d3d came out just a few years ago. for older games you should be good to go, before i had a vulkan-capable card i ran all kinds of older games, usually without having to tweak anything. in a few games i had to change a game setting to use D3D9 instead of 11.
Do you remember what the module was called as any directx game defaults to using the igpu for dxvk and there seems to be no option(in lutris) other than to outright disable dxvk.
other than to outright disable dxvk
That's exactly what you want. DXVK is the "new" DirectX to Vulkan translation layer (that's where the name comes from), and if you disable it you will be using the DirectX translation layer from Wine which uses OpenGL
I never figured out how to disable DXVK so eventually I just made a 2nd wine prefix without DXVK for games I run in OpenGL.
However if your GPU doesn't even support Vulkan then you shouldn't be using DXVK at all so why would you not want to disable dxvk?
hmm, not sure… i've heard it referred to as "wined3d"? when i had a non-vulkan card it usually wouldn't try to run vulkan so i didn't have to mess with it. what result does disabling dxvk have?
in steam you can put PROTON_USE_WINED3D=1 in the launch options, but this doesn't help for non-steam games
Disabling DXVK is the way to do it in Lutris. It's in the Runner Options tab for the game settings. If you create a new Wineprefix using WINEPREFIX=~/.local/share/wineprefixes/newprefix wineboot, it will use WineD3D (the D3D➜OpenGL converter) by default. It's what Wine uses for all Direct3D APIs up to Direct3D 11. DXVK is a completely separate project to Wine, but Lutris and Proton bundle it and use it by default. Lutris is completely usable without Vulkan, despite the scary warning.
You can actually get Vulkan on GCN 1 and 2 cards through the AMDGPU driver set. It's just not enabled by default because support is in beta status limbo. YMMV though because a reason I remember upgrading from an R9 280 (HD 7950 refresh) was to get better driver support.

This. Can confirm that it will work as I've used vulkan on an old Radeon HD7770, also on a R9 390. Basically you need a kernel parameter in the bootloader config to enable AMDGPU driver.
I used this trick on my old laptop, which my dad now uses as a light gaming PC. Works well for StarCraft and Rocket League! Even DOOM (2016) works well on low/medium settings. Don't remember which GPU but it wasn't very high powered even when it came out in 2014.
Sigh, miss my little R9 270
Happy to be corrected but I'd be surprised if it was possible to automatically convert between the two APIs - they are structured very differently, and I wouldn't expect there to be many 1-to-1 mappings
