Can't see appearance in desktop settings to hide mounted drives

What I have:

I am running Ubuntu server 22.04.4 LTS 64-bit on a Lenovo E30.

I have the gnome 42.9 version running.

When I login, I use the ubuntu option (selected toggling (F1)Here is a list of the installed desktops:

ls -l /usr/share/xsessions/-rw-r--r-- 1 root root  259 May  9  2022 gnome-classic.desktop-rw-r--r-- 1 root root  296 May  9  2022 gnome-classic-xorg.desktop-rw-r--r-- 1 root root  248 Apr  7  2022 gnome.desktop-rw-r--r-- 1 root root  256 Apr  7  2022 gnome-xorg.desktop-rw-r--r-- 1 root root  292 Apr  7  2022 ubuntu.desktop-rw-r--r-- 1 root root  300 Apr  7  2022 ubuntu-xorg.desktop-rw-r--r-- 1 root root 6832 Feb 16  2021 xfce.desktop

What is the problem:

I want to hide the mounted network drives off the desktop.I cannot see the appearance setting in the Settings window to do this. Numerous sites have said this is where I need to hide them.

What have I tried:

I have tried to login using the gnome option but get an Xsession error: unsupported number of arguments (2); failing back to default at which point I cannot select the ok button and I have to power off the system.

Thanks,Tom
