As I understand it, you would basically have to write your own display library from scratch which would be a big time sink for a solo developer. I'll do a bit more research on this for sure!
It's not that hard to do something basic. It took me about a day to do this one:

https://github.com/arg08/pico-mode7

That one isn't VGA, it's TV-frequency RGB, but that's just a matter of tweaking the timing constants.

It also has far more complexity than you would need as it's emulating the Teletext character display format (only 40x25 characters but with a fairly high resolution bitmaps for the characters).

(to be fair, I borrowed the logic for the teletext graphics from a previous project of 20 years earlier but the Pico video output I wrote from scratch)
