Most care have an inertia stitch (in the trunk I believe) Place a toggle switch in the circuit creating an open (same as the inertia switch or pull the fuel pump relay...no code should be generated.
No inertia switch on a 16 Camry. AFAIK Ford is the only passenger car that used them and that was 30 yrs ago.
Both good ideas regarding removal of the fuel pump relay and a toggle switch so combine both ideas and put an inline toggle switch for the wire of pin #30 or #87 of the fuel pump relay
