Bitlocker tripped on reboot

My current bitlocker hardware 'state' is stored with a single GPU (i.e. eGPU disconnected). If I reboot with the eGPU connected, bitlocker prevents it booting.

If I suspend bitlocker to 'reset' the hardware state (this link: https://egpu.io/forums/builds/clevo-n141zu-gtx-1060-6gb-strix32gbps-m2-adt-r3g-win10-timginter/#post-63644) then if I try and boot without the eGPU, bitlocker stops it!

How am I meant to handle booting with/without an eGPU and bitlocker? (I have tried searching in various places, but not much luck)

Cheers for any help!

Go into Local Group Policy

 

Computer Config > Admin Templates > Windows Components > Bitlocker Drive Encryption > Operating System Drives. Click "configure TPM platform validation profile for Native UEFI Firmware Configs and copy my settings below. 

 

This will weaken Bitlocker though, so be aware of that. This should fix it though.

@se12897, you're a legend - thanks! For the slightly increased attack surface, this is easily worth it! (I'm not handling NSA secrets haha).

 

If anyone does stumble on this - after changing these settings, suspend bitlocker, do a reboot, to apply these changes
