Can I remove my oven's wire conduit to save space?
You have that much so that you can make the connection, then put the appliance in place. There's generally no problem with finding space for it, as it naturally ends up behind and/or underneath the appliance as you push the appliance in.
Rushing to shorten it may make it impossible, or very, very difficult to connect the appliance to power. Correcting THAT may require ordering replacement, uncut, feed wires. Proceed cautiously and deliberately.
If it's typical spiral flex, you cut across the spiral strip (so not straight across the cable as a whole) and usually have to bend the cable a bit to get the spiral to snap, then you need to insert a bushing to keep the cut metal from damaging the wires.
