Looks like physical SIM can now be converted directly to eSIM in Settings with 16.2.

I’m on Maxis and I saw the prompt in Mobile Data under SIM PIN.

Didn’t try to see if it’ll actually do it since I don’t want to make a trip to the service center to get another physical SIM.

Advanced Data Protection isn’t yet enabled for those outside of US until sometime in 2023. If you managed to enable it, do teach.
