If I am not mistaken, if Tor is disable then Whonix will not be able to access the internet as it was designed to function this way. If you want internet without Tor you would need to reconfigure Whonix and that will defeat the purpose.
I think we need to reevaluate what you are trying to accomplish. I know you have used Kicksecure and if this meets your needs then what is the idea behind Whonix for you? An extra layer of isolation? It might be best to use Kicksecure, learn more about the system and slowly integrate Whonix as I am assuming you are a beginner in the linux environment.
I hope you like it! I found it to be a great daily driver once I got accustomed to flatpaks. Just make sure you follow all of the instructions/guidelines in order to have it function as intended.
At a glance, secureblue is based on Fedora Silverblue Linux instead of Debian, and it uses the GNOME desktop environment instead of XFCE. It uses a security hardened (not privacy hardened) browser called Trivalent, instead of the privacy hardened (less security focused) Tor Browser.
You get secureblue by first installing Fedora Silverblue, and then you follow these instructions
