Variable valve timing is already banned. From the F1 2026 Technical Regulations:
5.9 Variable geometry systems
5.9.1 With the exception of wastegates, variable geometry exhaust systems are not permitted. No
form of variable geometry turbine (VGT) or variable nozzle turbine (VNT) or any device to
adjust the gas throat section at the inlet to the turbine wheel is permitted.
5.9.2 Variable valve timing and variable valve lift profile systems are not permitted.
5.9.3 Moveable trumpets are not permitted, and any geometry conveying the air from the
compressor outlet to the cylinder inlet must be fixed, except the throttles and the pop off valves.

So far it's just a dictator's blatant demagogy. Unknown what, if anything will become of it. Though apparently mentioning NA explicitly was carefully avoided.
