Its easier & cheaper for manufacturers to have just SSD installed even if the laptop has HDD support. SSD are all the rage, I mean Win10 can't even run properly from HDD anymore, so most consumers will prefer a 512GB SSD instead of 1TB HDD + 128GB SSD (almost similar cost).
Get the Asus K15 & forget about playing any heavy game. R5 5500U has a decent iGPU, can play light games (like Valorant, FIFA 22, even AoE4 at minimum settings) & 4-5 year games pretty well.
I mean, if you are fine with 30fps gaming at 768p, maybe you will be fine. Apparently, it has expandable RAM, 4GB soldered + 4GB in the slot (change this to 8GB at least as the iGPU will block 2GB RAM to be used as VRAM).
