Low Clearance for P-Trap at Sink

I am trying to install a new bathroom vanity with a lavatory, however, the house drain is too low to install a standard P-trap without cutting a hole in the shelf of the new vanity. Is there any alternative to a P-trap that is lower clearance? I have read on the internet that S-traps are not allowed because they will siphon water out of the trap. Any suggestions would be appreciated.

I don't know that I've ever seen a vanity that has a shelf unit in the center where the plumbing is supposed to go. Can you give us a picture of the unit and maybe a measurement of how high the center of the pipe outlet is from the finished floor?

Open the wall up and raise the drain line.
