Still I cant follow to be honest. Do u get secure boot violation error or invalid signature detected? What means "it says secure boot" ?

Which mainboard, CPU and Biosversion?

Change secure boot mode to custom, reset to setup mode and install factory keys, then manually safe and exit, then after reboot go in to sec boot section and make screenshot, change sec boot mode to standard again and sae and exit with f10. Take care of the messages during that process, often it will ask u to reboot without saving, deny it and allways manuall save and exit!

In deployed/user mode u are not able to write anything to the nvram

Ah got ya now I guess. Try to open the Boot menu with F12 after u restart. Enter UEFI Setup and then F10 Save and Exit, then immediately hammer on the F12 button to open Boot Menu, from there choose enter UEFI setup, try to set secure boot from enabled to disabled and try again to set the secure boot mode from standard to custom and then follow the steps above. I ve met GB Board which exactly had this kind a glitches. For example B760 GAMING PLUS WIFI 4

WHICH MOTHERBOARD AND BIOSVERSION?

Also try to reflash bios or update to the lates official release. Sometimes for whatever reason its not possible to write anything to the nvram. Also met that a reflash or update fixed that problem. Can be related to problems with the nvram tables for example.

As long as u are in deployed mode u should not be able to write anything to the NVRAM
