This is the procedure that I used for my 2021 4R TRD ORP.

Drove home from the dealer and with ~11 miles on it changed the oil to Royal Purple break-in engine oil. After ~50 miles I ran the 4R between 1,000 to 3,500 rpms keeping it very varied for ~500 miles. I then changed the oil and filter to the factory Toyota 0W-20 oil. I will do 5k OCI's going forward.

When draining out the break-in oil and examining the pleats in the oil filter - I did notice some very small metal particles. I am pretty confident the rings have seated nicely.

Also, it might be a placebo effect, but I don't notice the notorious "tick" that the current 4.0L V6 is know for. I do notice this "tick" on my 2019 4R - I broke that truck in following the factory guidelines - except for doing the first oil change at 2,500 miles.
