Still does not make sence.
You are talking about CAN bus.
A **bus**. That can have multiple nodes.

You do not 'switch' the bus. You can have multiple busses if each bus is either in a high load or many nodes.
With your 8 channels, do you mean that you want 8 CAN busses?

What do you mean with (de)activated?

What do you mean exactly? CAN doesn’t work like a signal you can switch between channels. It’s a shared differential bus (CAN_H and CAN_L) that all nodes connect to. You don’t switch the bus, each device connects through a CAN transceiver, and the bus stays continuous with proper termination. What’s your use case?
