Can-Bus with Manta M8P V1.1

this is a feature that is also advertised on the homepage and in the sales documents, but there is no documentation on how to use it.
How is the Can-Bus functionality activated when using a CB1 + M8P + EBB xxxx?
Not a word about it in any documentation from Biqu or BTT.

Start by gathering the CAN-Bus activation details for the CB1, Manta M8P V1.1, and EBB setup referenced in the issue, since no documentation files or tests are named. Done means adding clear usage documentation that explains how to activate the functionality for this hardware combination.
