Hey there! Nice to meet you!
Since you were able to request a security info change, your only option is to wait for the 30-day restriction state to complete; but just as you mentioned, if the hacker has their email or phone number linked to your account, having them in full control over your account, they can simply cancel your security info change request.
If this happens, you will need to try requesting again, and hopefully, the hacker will not notice.
Unfortunately, it is also not possible to expedite or bypass the 30-day restriction state.
However, if the 30-day restriction state is complete, you will be able to remove the hacker's security info email/phone number from your account using your newly added security info.

Thank you for your understanding! Please let me know if you need anything else.
