Is it possible to disable mouse move without disabling click and scroll? I want to make mouse pointer freeze at a point but click and scroll using wheel should work.

There is a xinput command that manipulates X devices, whose list can be obtained with

 xinput --list

Henceforth id=10 for the mouse assumed, that is seemingly true for modern Xorg releases.

Solution (using property names):

 xinput set-prop 10 'Device Accel Constant Deceleration' 65535

Return to normality:

 xinput set-prop 10 'Device Accel Constant Deceleration' 1

Solution (using property numbers):

 xinput list-props 10

Find
Device Accel Constant Deceleration (p):
in the output listing, where p is a decimal number. Now substitute it into:
 xinput set-prop 10p65535

Return to normality:

 xinput set-prop 10p1

Very late to the game, but the low-tech solution here is to put a bit of tape over your mouse light. That will "disable" the pointer but keep the buttons active, and doesnt mess around with the xinput settings.
