No, it is not recommended to replace a four-prong plug with a three-prong plug.

The fourth prong in a four-prong plug is a ground wire that provides an additional layer of protection against electrical shocks and electrical fires. The ground wire is typically green and connects to a ground pin on the outlet, which is designed to redirect excess electrical current away from your appliances and into the ground.

By removing the fourth prong and replacing it with a three-prong plug, you would be removing this important safety feature and potentially exposing yourself and your appliances to the risk of electrical shock or fire.

If you have a three-prong outlet and need to plug in a four-prong appliance, you should consider having a licensed electrician install a new four-prong outlet that is compatible with your appliance. This will ensure that your appliances are properly grounded and protected from electrical hazards.
