Hello Blake,
You can try hiding Bitlocker Management from Control Panel via GPO:
Navigate to User Configuration > Policies > Administrative Templates > Control Panel and edit the “Hide specified Control Panel items” policy. After you enable the policy, you have to change the “List of disallowed Control Panel items” and add “BitLocker Drive Encryption.”
