At this point, I'd be surprised if there was't official FSR4 support for RDNA3. AMD has too many current products running tha architecture not to implement it. Especially since they already have a version that works. When's the FSR Redstone update dropping? I'd think it would rear it's head there.
Edit: It seems like Valve built this like Nintendo did the original Switch and they did with the original Steam Deck. The Steam Deck used an APU that AMD designed for MS Surface tablet and then MS backed out of the deal. So they got a great price on the chip. Nintendo got great deal on the Tegra X1 because Nvidia was looking to off load them. They look to have an old Hawkpoint APU with the iGPU disabled and 110w version of the 7600S. I know AMD thought they'd make more head way on the low in laptop space with RDNA3. It's why they went with a monolithic die.
Side note: I always thought AMD left too big of gap between Navi 32 and 33. 64 to 32CUs is too big a gulf IMO. I always thought they should have a 48CU die in between the two. There was only an 8CU gap between Navi 22 (40CUs) and Navi 23 (32 CUs).
