Resolve and GPU

I used to be able to use Resolve on my desktop with on-board graphics (HD 4000) but it seems to not be supported on the newer versions of Resolve.
I also have the Blackmagic Intensity 4K card in the same computer. Is it possible to use that to make it able to use Resolve on my PC? I'm thinking not, but thought it may be worth asking. Possible to use the Intensity 4K instead of buying a video card? Or get Resolve to work with any other work-arounds? Or maybe with an older version of Resolve? If an older version, are they still available to download? And which version might work?
I'm not editing anything fancy. Just Microsoft Teams-recorded video captures.
