NOTE: Because BitLocker is a Microsoft encryption security product,
Dell neither stores nor possesses the ability to provide a recovery key.
Dell cannot circumvent the Microsoft BitLocker Recovery Key process.
Dell devices are NOT encrypted when shipped from the factory.

You will need to Recover Bitlocker Key from Microsoft account

BitLocker likely ensured that a recovery key was safely backed up prior to activating protection.
There are several places that your recovery key may be.

In your Microsoft account: Sign in to your Microsoft account on another device to find your recovery key.
This is the most likely place to find your recovery key.

Once you have key write it down so that you can go to your system and suspend bitlocker.  This is especially important if you are attempting to update bios.

This subject usually comes up because auto bitlocker is enabled from the factory
after OOBE with microsoft account.

Automatic device encryption has Windows to encrypt the system drive automatically after you completed the setup of your system with MSA (microsoft account).

Beginning in Windows 8.1, Windows automatically enables BitLocker Device Encryption on devices that support Modern Standby.
With Windows 10 and 11, Microsoft offers BitLocker Device Encryption support on a broader range of devices. These include those that support Modern Standby, and devices that run Windows 10 Home Edition or Windows 11. All computers that Dell currently ships are Modern Standby compliant and the above applies.  A registry key that Dell leaves in a neutral state controls this behavior, neither prohibiting nor enforcing encryption. Windows interprets this as approval to encrypt.
