Is there some grub magic I need to do? I assumed this would be

When I switched from nvidia to amd, many years ago, it was seamless.
But that was older hardware, I didn't have two graphics cards (a builtin
and a discrete), and I am using the radeon driver with an amd cpu, not
an amd card with an intel cpu. Anyway I did a quick search and found
this link that mentions something called prime that seems to do
something like what you want.
