Automating usd from Audio2face animation in runtime inside of UE. This is for rendered sequences

I’m currently building video rendering application using Unreal Engine 5, and gonna use Audio2Face to make lipsync of metahuman.
Generally, to make it, I need to create a usd file containing the lipsync animation generated from Audio2Face, import it in Unreal Engine, and then insert it into the level sequence to be rendered.
And it works very well manually.
This is the link what I referred for this.
https://docs.omniverse.nvidia.com/connect/latest/ue4/manual.html#importing-usd-animation

However, I would like to automate this operation.
Problem is I cannot find any solution to import usd file automatically.
In other words, I want to import the usd file into Unreal Engine in animation asset format using python script or blueprint.
Is there a solution for this?
