[Risolto] Abilitare super utente (su) e disattivare sudo

Ciao ragazzi,
vorrei attivare il super utente, disattivando sudo. Sapete dire come si fa? Mi ricordo che nei vecchi Fedora per accedere a zone protette si utilizzava solo il super utente.
Questo è il mio sistema:

[[email protected] sbin]$ uname -a Linux dell 5.2.18-200.fc30.x86_64 #1 SMP Tue Oct 1 13:14:07 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

[[email protected] sbin]$ groups andrea wheel

Questi sono i gruppi presenti:
