Not possible : either the file is a symlink or it is of unknown type.
I have made a proposal for you to try, available on :
http://jp-andre.pagesperso-orange.fr/execlink.zip
(however you will have to adapt the readme, which is related to another plugin)
IMHO this does not add much value to the standard "Unsupported reparse
point".

Title:
ntfs-3g Unsupported "Archive" reparse point
Status in ntfs-3g package in Ubuntu:
New
Bug description:
######## Description ########
I believe I've encountered a new type of reparse point that's unsupported by the current ntfs-3g library. I've tested this with a basic Windows 10 installation, and the reparse point seems to be on a Microsoft Edge executable file.
The current plugins (available at http://jp-andre.pagesperso-orange.fr/advanced-ntfs-3g.html#download) currently support reparse points for (all of which I have installed on my system):
1) System Compression
2) Deduplicated files
3) OneDrive
I attempted to invoke the "file" operation on a given Windows 10 file,
entitled "MicrosoftEdge.exe".
######## Expected Outcome ########
I expected to be able to read the file either in the form of a
"symlink" or a normal file.
######## Actual Outcome ########
I encountered the dreaded "unsupported reparse point":
david at david-VirtualBox:~$ file /mnt/windows_10/Users/user/AppData/Local/Microsoft/WindowsApps/Microsoft.MicrosoftEdge_8wekyb3d8bbwe/MicrosoftEdge.exe
Users/user/AppData/Local/Microsoft/WindowsApps/Microsoft.MicrosoftEdge_8wekyb3d8bbwe/MicrosoftEdge.exe: broken symbolic link to unsupported reparse point
Which I believe is a currently unsupported "Archive" reparse point,
which I've determined by running "ntfsinfo" on the file. It identifies
the File Attribute as an "Archive" reparse point:
