Thanks for answering my question about Rav Moshe’s psak, but the articles explained the reasoning and not the fundamental of my question, is the definition of hard cheese in Halacha the same as in Issur veheter, aged 6 months, or is a separate definition used for gevinat akum

Does the prohibition of Gevinat Akum not apply to cheese which is not aged for 6+ months? I ask because Moshe Feinstein says it doesn’t apply to non hard cheeses, and we learn from Halacha in issur veheter hard is defined as aged 6 months
