Any tips on making 720p more lightweight on Dolphin?

The best you can do for something like the Intel UHD 620 is make sure your laptop's Power Options in Windows is set to Performance. Not sure, but I believe Windows sets this automatically if you plug in your laptop's charger.

Other than that, no, not much you can do to lower the GPU requirements for Dolphin.
