The rig is a box-on-box type, it is the hydraulic move system that is optional.

A box-on-box design means that "it enables efficient rig moves on
trucks. This can be particularly useful for European operations , where road
load rules can be strict."

A hydraulic move system would mean that the entire rig has some sort of movable system that allows it to move a short distance without being disassembled...a short distance meaning it stays on the same drilling pad.
