Refer non critical java

I have looked through all the forums and have not found an answer other than no we can’t and I love webflow but will move off of it if I can’t do things to speed up might site on the java or css side.

It is fast already but when I integrate third party apps I know it will slow down so I need to be able to optimize the rest of the site the best I can.

Here’s my question, can we defer non critical java?
