Without checking, this is likely due to NTFS having a proper driver in the kernel these days. As such Fedora might well have dropped the ntfs-3g package as no longer being required, and thus its inclusion in EPEL is now more difficult, as EPEL is populated from rebuilt Fedora packages. I didn’t notice the driver being added in the RHEL10 release notes so that is why you are thinking you “need” the ntfs-3g driver.
