I don’t think that the Nextcloud Client can do much about that. This functionality is handeld on the OS level or more precisely by the driver for the filessystem. On Linux the NTFS-3G is used to mount the file system into user space via FUSE. All relavant features should be supported in Linux…
NTFS-3G supports all operations for writing files: files of any size can be created, modified, renamed, moved, or deleted on NTFS partitions. Transparent compression is supported, as well as system-level encryption.[6] Support to modify access control lists and permissions is available.[7] NTFS partitions are mounted using the Filesystem in Userspace (FUSE) interface. NTFS-3G supports hard links, symbolic links, and junctions. With the help of NTFS reparse point plugins, it can be made to read chunk-deduplicated files, system-compressed files, and OneDrive files.[8] NTFS-3G provides complete support and translation of NTFS access control list (ACL) to POSIX ACL permissions. A “usermap” utility is included to record the mapping from UIDs to Windows NT SIDs.

Unfortunately you did not give us any details what exactly is not working for you and which Linux distro in which version you are using. What I can say is that when you use a current Windows version, it is generally a good idea to also use the most recent NTFS-3G version. Sidenote: Starting with kernel version 5.15, NTFS support has been natively integrated into the Linux kernel.
I also did a quick Google search on “NTFS-3g” and “NTFS Reparse Points” and actually didn’t find much about any issues with it. So I can only say that it should work in principle…

And here is someone who had problems with it in an older Ubuntu version…

…but this is probably no longer relevant in newer versions.
