How to exclude unused PyQt5 modules when compiling?

Question

Python

Everyone is well aware that when creating a binary from a PyQt5 application using PyInstaller, the size of the binary is very large (30mb, or even more)
I am making an application that uses only buttons and text lines. But when built, pyInstaller includes a bunch of unnecessary libraries (like WebSockets, OpenGl, Tiff, Network, etc.) that are not used anywhere.
How can pyInstaller be configured to exclude unnecessary libraries? I am sure that the size of the binary will decrease at least twice.
