Exactly, we are helping you by not giving some half fix which can be abused in two seconds and actually giving you a good solution. It might sound hard but this is really just an issue with your resources and removing any tools to abuse this would not be a solution.
We are not going to spread some fake “fix” which blocks the devtools since that will lead to people going “waaa” when people still bypass it since they think the fixed the issue, the real issue can be fixed by not trusting the client. There are topics about this already see How hackers can exploit your servers and what to do about it which are trying to help the community fix such issues.
