You can use the controller and the Logitech G29 at the same time (or used to) as I found out to my cost.
Placed the controller next to me the put some food down after a pit stop, car kept turning left! Left a bag of Doritos on the controller… admittedly this was setup up as standard with triggers as the pedals and not gyro
Edit: Sorry - I realise you don’t want to have the wheel at all. And as others have pointed out, the pedals go through the base!
