Brave and Uphold Wallet

Hello,

I am facing the following issue regarding Brave rewards and Uphold wallet.
I connected the Uphold wallet at 2 laptops (A, B) and two smartphones (C,D). The sync took place and everything went well with the process. Unfortunately, I don’t have any access to the laptop A anymore and I unistall BRAVE from there. Then I bought a new laptop (E) and I tried to connect the wallet but I assume that I can’t since the 4 devices rule is on.
How I can disable the Wallet from Laptop A without having any access there anymore (and as I said unistalled).
