We're currently on 2.1.7 EE, and trying to find an extension for Facebook Pixel ID. We were contemplating this one: https://marketplace.magento.com/i6media-facebookpixel.html#bazaarvoice.reviews.tab however, it only specifies Community Edition for compatibility.
There really aren't any on the magento marketplace specifying EE -- does it matter?
For the most part extensions that advertise compatibility for CE are likely to be compatible with EE (albeit they won't support any EE specific features). This is because EE is simple CE + additional modules.
I don't have any knowledge of this extension, but it sounds like functionality that is likely to be compatible with EE. One downside is that in order to mark an extension as compatible with EE you have to be a Magento partner so often it's just a case that a vendor has decided not to make that commitment.
Always best to send a message to the original vendor to get confirmation.
