SFC reads from the C:\Windows\WinSxS component folders and manifests. If you modify or remove system files, follow the basic rules:
- When you replace a file, replace the same file in the last WinSxS folder containing it. Use folder Search.
- When you remove a file, remove the same file from the last WinSxS folder.
- After you apply a Monthly CU update, check if your changes got overwritten and re-apply them.
- When you replace a file, replace the same file in the last WinSxS folder containing it. Use folder Search.
- When you remove a file, remove the same file from the last WinSxS folder.
- After you apply a Monthly CU update, check if your changes got overwritten and re-apply them.
I just installed windows 17763.1 (1809 first build).

then I changed the rights to the system folder (systemapps\sechealthui) and deleted it. At the same time, I made a backup of it.
I deleted all folders and manifests in winsxs containing sechealthui in their name
screenshot of verification after removal:

I found a solution to this problem.
In general, as it turned out, it was necessary to delete not only manifests and all directories associated with the deleted system file/folder in winsxs folder,
and also all related directories in the registry along the path: "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SideBySide\Winners".
If done correctly, sfc /scannow will eventually ignore a specific system file/folder path.
I also forgot to add that in some cases cleaning is also required along the path in the registry: "HKEY_LOCAL_MACHINE\COMPONENTS\DerivedData\Components"
In addition, clearing winsxs paths and manifests associated with a system file/folder is not necessary, since by editing the registry, sfc /scannow will ignore them.
However, you can also clean up winsxs to save space.
