XPS 8960, Factory Reset with Bitlocker

I want to do a factory restore on my XPS-8960 which was delivered with Windows 11 Pro.

Planning on using the F12 Boot Options and SupportAssist OS Recovery options.
The Boot Mode is UEFI and Secure Boot is On.

From Bitlocker Drive Encryption, Operating System Drive shows that Bitlocker is Off.
On my other two internal hard drives (D and F) Bitlocker is waiting for activation.

And from Computer Management > Disk Management, both D and F drives shows NTFS (Bitlocker Encrypted).
I find this very confusing as I have no activated Bitlocker.

However, I would like to do a Factory Reset but am concerned that Bitlocker may cause problems.

Is there a recommended procedure to follow, i.e. from within SupportAssist or Windows Recovery ?

My thought is, that using SupportAssist I should get a complete factory reset.

If using Windows Recovery, I may only get a Windows 11 Pro reinstall.

Any thoughts is greatly appreciated
