While its feasible, its probably not worth it. Instead, make a program
that locks the person in the shell maybe, or locks the whole calc.

What exactly do you mean by "take your games"? Why do you mind other
people playing your games?? Are they shareware that you have paid for or
something?

Umm... do you have any idea what you are talking about?
R=read
O=only
M=memory

Oh...well, yes it is possible to do it, probably there is a byte(s)
somewhere in RAM used by the TIOS to figure out exactly what menu is
on... You can use a TSR to test that byte(s) and change them if they
signify the link port.
A cooler idea is to check the keys being pressed, and disable 2nd-xvar
by checking the key port for x-var and if it is held down, call get_key
(thus destroying the x-var keycode which is stored as the last key
pressed)! I'm not sure this would work, but i'm there is a possiblity...
BTW, you'll probably want to use Usgard or Rigel, NOT CShell. Because
you'll have to change the backup for CShell to use a TSR, and its lots
of unnessecary trouble.
