Should I add modules to a unity engine-update every time I update unity engine?

Hi,
I’m really tired of updating unity engine almost every two weeks,
it takes so much data consumption and takes so much time, since my internet is only 0.5MB/s.

so can I reduce update size by not adding modules like visual studio and androids sdk, ndk and jdk? is there a way i can move modules from last update to the new update, without issues?

You dont have to update unity often. If you want to update for long time you must try LTS(Long-Term Support) version of Unity.
