Abaqus - Restart and change contact control

I would like to change the contact control damping factor during my simulation, but despite using the function model change I failed in changing it, simply the input file wont change. But it is clearly possible to change contact interaction after a restart, but how is not well described in the manual. Could anyone provide me some guideline to do so, because I am at a dead end. Thank you all in advance
