This will read all Ethernet interfaces on a system and determine based on what you call your 802.1x Profile if it is present on all Ethernet interfaces and report it into jamf as a string. You can then create a SMART group that looks for the word false so if any are false you can then use a policy to make the profile apply to all interfaces

# This script will find the system profile and determine whether it is attached
# to each interface and report that information. This is formated to be used
# with jamf as an Extension attribute. Expected output would be as follows:
# || en3 - True || en4 - False || en5 - False ||

# I'd like to give a very special thanks to Mosen who was so influencial
# in making this script a reality. Thank you so much for asssting with
# this project and it is my hope that this truly solves our 802.1x issue
# on the Mac side and allows us to move forward with the project. We
# decided to switch from EAP-TLS to PEAP-MSCHAPV2 because the user
# will still need a domain bound computer which can only be done by our
# IT Staff and will need the cert from our CA. This script does work with both
# protocols though
