In my possesion I have a wallet.dat that I have tried to brute-force with hascat, jonh the ripper and btcrecover for more than 10 months the final result is null, I would like to know if you have information to share or additional help.
Basically, your only option is to try and bruteforce it... or engage the services of someone else to bruteforce. There is no "magic bullet" that will allow you to access your funds. If you haven't been able to bruteforce the password in the last 10 months, then there is a good chance that the Hashcat mask(s) you've been using is/are no good.
Can you please share here what hashcat settings you have tried?
