Is editing of the Driver Station/Running a non-DS program allowed?

My team would like to know if teams are allowed to modify the Driver Station software in any way, shape or form.
Another question too- If at a competition, Would a team be able to run a program in addition to the Driver Station on the Driver user on the Classmate??? :confused: :eek:

You are allowed to modify the Dashboard code, but not the Driver Station code.

You allowed to run additional programs on the classmate as far as Iā€™m aware. You are also allowed to use additional computers.

No for modifying the driver station per [R58] and the blue box under [R58].
