The answer
No. The permit deadline prevents the signed approval from being executed after that time. Once a valid permit has set an on-chain allowance, the allowance generally persists until spent or changed under the token’s rules.
What to do next
Inspect the existing on-chain allowance and revoke or lower it if you no longer trust the spender.
