Temp Wallet Disable after compromise

My wallet has unforunately been compromised.
I have created a new wallet, and have sent most of the assets to the new wallet.
There remains one rather larger problem.
I have assets in a liquidity pool that is locked for 90 days, and I cannot back them out. Incurring penalties is not even an option.
Is there any way I can temporarily shut this wallet down until the time of vault opening, and see if I can get my stuff out of there quicker than the crumbs that compromised the wallet can?
