@Matthew Hedrick,Thanks for posting in Q&A.
From your description, I know that you are confused on silent BitLocker policy settings and want to figure out.
Based on my research, if you want to silently enable BitLocker via Intune, there are two methods you can configure it and settings you can refer.
1.Endpoint security Disk encryption policy
- Require Device Encryption = Enabled
- Allow Warning For Other Disk Encryption = Disabled
2.Device configuration Endpoint protection policy
- Warning for other disk encryption = Block.
- Allow standard users to enable encryption during Microsoft Entra join = Allow
- User creation of recovery key = Allow or Do not allow 256-bit recovery key
- User creation of recovery password = Allow or Require 48-digit recovery password
Hope this can be helpful. If there is any update, feel free to contact me.
