HP 745 G5 MS Autopilot Enrollment - Clean EC?

[VHS]

I recently purchased a small batch of 10 HP 745 G5 notebooks; it looks like some weren't removed from the remote management when they were decommissioned, and they want to enroll with the corporate domain when Windows OOBE starts.
I really don't know if it's Intune, autopilot, or what, but during Oobe, it requires me to log into the company domain.
Since I have some that are clear and some that are managed, can I re-program the BIOS and EC chips of the locked ones with unlocked ones?
Rewrite the SN with DMFit or???
I can probably send the serial numbers to my guy, who can go back to his vendor, who can go back to the company, but for a handful of old notebooks that aren't even Win11 certified, I'm not sure it's worth the trouble.

Hello,

Have some HP Laptops and even after removing bios password and trying to install windows it requires me to login to company domain and the strane is that the Bios password is back 🤣
What sorcery is this.
