For example, any Continental tire more than two years old is not hookless-compatible.

Some wheel manufacturers like Zipp make the effort to list all of the tires which are certified with their wheels, and those that are not.

One needs to make certain that the particular tire in-question is compatible with hookless rims. Also, the maximum allowed pressure of a tire may be different on hooked versus hookless rims, which is another facet to pay your attention to.

Pete, you will want to be more circumspect about providing potentially-dangerous advice, lest you get someone hurt.
