Hi,
BitLocker in Windows 10 has two requirements in regard to an operating system deployment:
A protector, which can either be stored in the Trusted Platform Module (TPM) chip, or stored as a password. Technically, you can also use a USB stick to store the protector, but it's not a practical approach as the USB stick can be lost or stolen. We, therefore, recommend that you instead use a TPM chip and/or a password.
Multiple partitions on the hard drive.
For more information, please refer to the following article:

Hope above information can help you.
