HMGs have an ability - I don't remember its name but the icon looks like an "eye". So, deploy the HMG, activate the ability, the HMG and crew will become camouflaged and then a "Hold fire" button appears. Press it and they will not fire unless you cancel the "hold fire" order.

Thats only possible outside of buildings, but you don't need any cover and can camouflage them anywhere.

If it's inside a building it will camouflage itself and shoots automatically at any enemy in range, there is no way to prevent that.
