Compared to OBJ context, you will not be able to enable the texture animation at shading level.

If you want to enable texture animation, you must leave the node connected to the RS Texture node (offset or rotate input).

You can easily identify the USD version of the YMA Animate Offset-Rotate custom node. It has the Time parameter locked and contains a description how to animate the RS Texture.

In Solaris, you can use YMA Assign Material LOP node to easily swap between materials:

In order to not affect the stage performance, the materials won’t add Time Dependency into your graph.
To animate the texture projection, add YMA Animate Offset-Rotate LOP node to your graph.
It will automatically find the YMA_CustomTimeNode primitives on your stage and add animation using the same UI as shading level.

Advanced Tip:
You can dive inside the YMA Animate Offset-Rotate LOP node. You will find the Edit Material Properties node that updates every YMA_CustomTimeNode primitive on the Stage.
You can also create custom overrides and link the time update for custom time steppings.
