2 Identical MacBook Pro 9,2... One won't boot from USB after choosing OCLP EFI from Boot picker

2 Identical MacBook Pro's. One my daily driver that works great. Running Ventura 13.7.1. It will boot into the USB Ventura Install to the recovery options. But the other when I choose the EFI option for OCLP the computer always boots up from the internal HD. I have made USB OCLP install from both computers, and neither boot from USB, only going to the internal HD. I booted up the computer with a CATALINA boot USB and it starts up and will allow install of Catalina, if I wanted. So that works. I reset PRAM, SMC.... Still hitting a wall wondering why I can't choose EFI for OCLP from any USB setup for a 9,2 and not get it to boot the USB Recovery for Ventura 13.7.1. I can hit the correct key combination to get into INTERNET RECOVERY...... At a loss
