Are Foundation year scholarships a thing?

I'd like to know if any University offers a Foundation Year Scholarship to International students who'd like to study in the UK?.

Have you searched the websites of the unis that offer the foundation year?

A number of unis offer a partial tuition fee waiver for home students for foundation years as I recall. This doesn't really make much difference typically as said home students are normally having tuition fees paid by SFE loans from SLC, but it's something. They might have something similar for international students, where it would make a much bigger difference!
