I would suggest you get it cleared with the Tech Department.
The rule book reads as follows:

FIREWALL
Alterations prohibited unless expressly permitted in this section.
Firewall coverings prohibited. Where heater/air conditioning
units have been removed, area must be covered with minimum
.024-inch steel or .032-inch aluminum, including rear hood seal/
flange, as on GM A-body. Minor firewall modifications permitted
to C5 and C6 Corvettes for transmission installation. Roll cage
tubing may run across top or side of inner fender well/strut
tower and attach to frame horn. See General Regulations 7:4.

General Regulations:

7:4 FIREWALL
Each car in competition must be equipped with a minimum
.032-inch aluminum or .024-inch steel firewall, extending
from side to side of the body and from the top of the engine
compartment’s upper seal (hood, cowl, or deck) to the bottom
of the floor and/or belly pan. Firewall must provide a bulkhead
between the engine and/or fuel tank and driver compartment.
All holes in firewall must be sealed with aluminum or steel. In
certain instances, fiberglass, carbon fiber, or other composites
may be used. See Class Requirements or consult
NHRA. Use of magnesium prohibited.
