The effect of applied pressure on fractional Chern insulators (FCIs) in moir\'e TMDs is numerically studied, indicating that can enhance the many-body gap these topologically ordered phases. This supported by showing that, within region stability FCI, quantum geometry topmost flat band almost satisfies ideal condition.
