How can I disable the Alt+Num default behavior.

I have some custom keybindings globally on my device that uses Alt+1, Alt+2, Alt+3, Alt+4 as some tasks. But firefox also uses Alt+Num as the shortcut to change current tab to tab-[Num]. I would like to disable this behaviour so my system's shortcut works instead of firefox's shortcut in that case.

How can I achieve this behavior?

I don't believe there is a built-in way to do this. you can edit the Firefox source code to achieve what you want but most importantly if you have global key binds then Firefox shouldn't even receive these keys.
