The point there is to use a better wallet.

Network rules are not bound or limited by third party developers failing to implement basic functions in their software. Being able to replace an unconfirmed transaction is an increasingly basic function of bitcoin. If your wallet does not allow you to do that, then find a better wallet which does.
which wallet you recommend that support RBF, i want to send a transaction and make it final with RBF disabled
how to do this?
even if the node is full RBF is this possible
in other word how to make a transaction final without any possibility to double spend it
