I apologize for not being able to reply to your question promptly.
Your father can not deprive his children from their share of inheritence even if they are disobedient. The only way the children will not inherit is if they are not Muslims.
I understand that the son does not respect his parents and is very rude and disobedient so what your father can do is distribute his entire estate within his life. This way there will be nothing left for distribution after the demise.
And Allah knows best.
