Settings on Live USB

I need to make a flash drive with a live version of Linux. The problem is that I would like to change some settings in the system.
I've tried using distroshare ubuntu imager, I've managed to install applications but when I turn on live the default settings are applied (wallpaper, taskbar etc).

Is there any option to change "live session user" settings?
I also tried to make persistent live, it works, however I use this linux on many different laptops every day, each time logs and other unnecessary things are downloaded to persistent memory.
A possible solution would be to add a script that would remove everything except my settings from persistent memory, but I don't know how to do that. Please help

I might be wrong, but I don't think it is possible to do what you want to.

They're not unnecessary, quite the opposite, how do you think persistence works? Magic? No, it saves logs and necessary stuff to keep your settings across reboots and computers, otherwise is just a regular Live OS.

Ok, I think you don't understand me. Maybe there is a way to make persistent live os, change settings etc and then make this persistence read-only? I need live OS with just a little tweaks like wallpaper, position of icons and taskbar.

In that case, you could use some distro which uses a COW(copy-on-write)partition, like openSUSE Leap. Last time I tried, installing programs and making updates didn't work, but for the purpose you mentioned, like customizing the desktop, and saving Wi-Fi password did https://www.opensuse.org/
