using SHAKE for solvent only

Hello all,

I am currently studying HF in a box of TIP3P water and want to get the
IR spectrum of HF. In order to do so I need to let the HF bond free of
constraints. But TIP3P model was designed to have fixed bondlenght so I
was wondering if it would change the results a lot if I leave it flexible.

I would like to run both simulations (H2O with varying/fixed bondlenght)
in order to do so, I would like to know if there is a way to apply SHAKE
to the solvent only ?

Thank you for your help,
