[REQUEST] HP 250 G5 (W4M72EA) Insyde F.48 Unlocked BIOS

[Iosif]

Good morning.
I am new to the bios modding community, and I would like to request an unlocked Insyde F.48 bios for the HP 250 G5 laptop.
I need to unlock advanced settings on this BIOS because I have to change the main graphics card from the integrated to the external graphics card (I've installed an Nvidia GT 1030 with an EXP GDC)
I have InsydeH20 rev. 5.0 BIOS.
I read online that to unlock the advanced settings you need to press a combination of keys while in the BIOS, 
I think I have tried them all (ex: Fn + Tab or Key A etc ...).  
None of these combinations unlock advanced settings!  
Then I read online that HP locks the advanced settings for security reasons.
Is there anyone who can help me?
