This might not be the right forum to ask this however I am going to take a chance......

I have deployed Office 2010 with Access (OCT)  to around 1000 devices.

I now need to remove Access on all these devices or make it unavailable so users cannot use Access.

Is there  any modification that I can do to the exiting OCT that will help me achieve the above result?

You can remove access from the installation using the admin tool (OCT) then use a /p to apply the change to the existing configuration. 

This is the link to the 13 setup, configuration will work the same way in 10 as far as I remember.

Here is the technet for the 2010 config.
