Nothing too crazy, i followed this guide https://xdaforums.com/t/guide-enabling-volte-vowifi-v2.4028073/
But instead of the Mi9T mbns, i used the pixel 4 verizon hvolte mbns. LTE, bidirectional calls, bidirectional sms / mms, and rcs are all working. You will need verizon to enable cmda-less features on your account. Visual voicemail is currently not working, but it's possible i just don't have it enable on my account any longer.
This is on a 512gb Taiwanese B model. I did try this on android 10 and 11, for some reason 11 had much better signal reception, but i decided to stick with 10 for now and run lineageos, no issues after 3 or so days of use.
