No, if someone has your seed phrase, it cannot be disabled. A seed phrase is a set of common words, often 12 to 24 words, whose spelling and order must be exact. If someone has your seed phrase, they have access to your account and all of its associated funds. The only way to prevent this is to keep your seed phrase secure and not share it with anyone. Even if you block or delete someone who has your seed phrase, they will still be able to access your account. The only way to protect yourself is to never share your seed phrase with anyone and to make sure it is stored in a secure location. If you feel that your seed phrase has been compromised, it may be possible to use a Tronx master key to disable the seed phrase, but this should only be done as a last resort.

I left him I blocked him

why are you still talking with the scammer?

So I should forget about the disabling master key When I asked someone He said I need tronx
