The Lenovo Precision Pen 2 is not explicitly confirmed as compatible with the Yoga Pro 7 (14.50", Intel Core Ultra 9 285H). However, the Lenovo Active Pen 2 is recommended for the Yoga Pro 7 14IRH8, which is compatible and enables precise writing. It is likely that the Precision Pen 2 is not supported, as Lenovo mentions the Active Pen 2 for this model.
