I have a couple of questions about a customized Distro I’m making for my dad (sending him a USB to install it from) that’s easy to use (he’s always been extremely tech illiterate - he only learned how to use a computer thanks to Linux, but that version of Ubuntu he had learned on is over 10 years old now) and I can connect to via Rust Desk that has a custom icon that says “help” (using Mint 22.1)

So far, the closest to success I’ve had is using Systemback - it perfectly copied the system as set up.

But, there’s just one big problem - the installer.

The installer, despite being a GUI, is not user friendly. Not only are there a lack of instructions (making it unintuitive on what you need in order to be able to click “next” even if you are basically tech literate), but it involves manually partitioning the hard drives into 3 partitions - there’s also no “erase all and use the whole drive” option.

My question is, can I edit or replace the installer Systemback uses, for something slightly easier, or if not feasible:

Can I use the terminal in Cubic to change a program’s icon, move the panel (optional), and pin a program to the panel, as well as set up Firefox to not have AI, change the search engine, font size, and bookmarks, as well as install uBlock? (I’d install Librewolf, except that it doesn’t store browsing history by default, which he relies on).
