Select Device security and then on the right side, right-click on an empty area and select New > DWORD (32-bit) Value, name it DisableClearTpmButton.
After that, double-click on the same DisableClearTpmButton and set its Value data 1.
Once done, click the OK button and then reboot your computer to apply the changes.
After doing this, you can create a new BitLocker PIN on your Windows 11 or 10 PC. As simple as that!
