How can i disable the Parallels Desktop Shortcuts?

I rarely switch between different views in Parallels, but I often find myself trying to use Windows shortcuts that trigger a switch from one Parallels view to another (for example, trying to insert a carriage return in Excel).

When I go into the Parallels options, the checkmarks for the "Parallels Desktop Shortcuts" are all disabled.

The help file doesn't explain why this is the case - it simply says "Desktop cannot be added or removed,"

I don't want to add or remove these shortcuts - i just want to disable them.

Is it possible to disable these shortcuts?
