Chassis battery circuit breaker to BIM? ISATA3

I have a downloaded document that shows battery box wiring and breakers for close to my year of 2021 ISATA3 (in a Mercedes sprinter). In the diagram, it says there is a 150A circuit breaker "under the driver's seat" for the circuit that joins the house battery to the chassis battery (#2 wire).

I think to access "under the driver's seat", I have to remove the driver's seat with tools. Do I have this right? Or is this elsewise generally accessible to be able to throw this breaker one way or the other?

Thanks, Tom.

You have it right -use a 10mm 6-point socket at the four mounting points of the seat and then tilt the seat back to access the breaker.
