If you load Tealium Asynchronously then the only marketplace tag you can utilize is the "Adobe Target (Async)" version but you can impement TNT synchronously in the utag.sync.js file. This is typically done by placing the at.js code or it's loading script in the utag.sync.js file. The utag.sync.js file is loaded independently and synchronously in the <head>.
Just to expand on @robert_sabec answer.
We have developed a Flicker Free Solution so that you can load utag.js asynchronously and then the flicker-free code synchronously using the utag.sync.js.
At present there is a new version of the Adobe Target Tag that is being developed, that will replace both the current tags.
This has the latest at.js code and will allow for integration with the Adobe Visitor API service as well.
I would advise not to put the at.js code directly into the utag.sync.js file, and to use the Flicker Free solution. If you would like to try the new beta version of the Target tag please either reach out to your account manager of support for them to enable it for you.
