Here is some info on the newer B58 version via BMW documentation:

This is confirmed in the new G05 X5 but not sure if it has been updated across the all models as of yet.

"The B58 debuted a few years ago but the updated iteration gets a new cooling system, head, timing chain, oil pump and a forged crankshaft. The block and air induction system have been modified, and the new high-pressure direct-injection fueling system is rated at 5,076 psi (350 bar), up from 3,626 psi (250 bar).”
