Can we limit for single link upload

1. if file size is larger than 2 GB, it will upload otherwise it will skip the upload. (I think we already have this option)
2. if file size is larger than 8GB, TC will skip the upload.

You can do both for needed hosts.

In "HOSTS" -> "Files" -> select needed host -> under "Other settings".

1. "Don't upload files smaller than -> set 2000.

2. "Don't upload files larger than -> set 8000.

Press "Update" button.

If needed do it for all used hosts.

This will only skip the files when uploading, it will create the post.

If you want to skip creating the post if main files are larger / smaller set those sizes in "Settings" -> "Process" -> "Files" then.
