How to make a separate render?

Question

Django

Hello. I do not quite understand how you can display a separate render of two elements.
I have two blocks on the page. Each block is rendered as a separate list. those. when rendering I give two lists

render(request, 'aboard/index.html', {'info':gen_chart(),'lter':gen_act()} )

How can I make the page render when loading, and then when the button is pressed, only one block is processed (i.e. the data changes only in one list, and the first list remains unchanged after the page is loaded)
