How can I factory reset a Surface Pro 5 that is bitlocker encrypted and UEFI password protected?

Question

I purchased a government auction that included quite a few Microsoft Surface Pros. I have reset a few of them, but one cannot be reset in a traditional manner. Holding down the volume down button while turning on the device does nothing- just takes me to the bitlocker password screen. I can only enter the UEFI settings as limited user due to it being password protected. Seems like there are no options other than to discard the computer. I'd hate for a perfectly working computer to become a brick because of this nonsense.

Is there any way around this that I'm missing?

The device was purchased legally and it just seems like someone in the government facility's IT department didn't know how to properly reset devices to factory condition (or just too lazy to do so properly). I have more computers that I haven't gotten to yet, so I'm not sure if this is the only one like this. I was hoping to not have to do anything to invasive (like ripping out the soldered SSD).

SP5 (2017) is no longer supported by Microsoft, so you can't even exchange it. https://learn.microsoft.com/en-us/surface/surface-driver-firmware-lifecycle-support
