[Help] OPX qualcomm band unlock

Okay so I've gotten the qualcomm unlock to work, but it only works on Stock, Freshly flashed, OxyOS; all other ROM I've tried have had Diag mode disable/unimplemented.
The problem is NVRAM is locked on Stock OxyOS, so on reboot the changes I made already get reset on reboot, so I had the idea of backing up the modem partitions using "Partitions Backup and Restore" and restoring them on boot/new ROM. I checked the SHA256 hash of a stock modem backup and my Modified modem backup and changes are there in the backup I made, but when I restore I don't get the bands back.
Does anyone have a clue how I can get these changes to stick?
Also is the Locked NVRAM an implementation in the ROM or HW of the phone? Can it be bypassed?
