The Quest 3 cannot do that, its depth sensor is far too low resolution to scan a face with a good fidelity level.
Unfortunately, it also means the quest 3 probably will probably never be very good at dynamic occlusion in mixed reality (ie: hiding partially virtual objects that are behind real life objects).
