How to change the authomatic renovation of a licence?

Avast Account (my.avast.com)

I have several active licences with Avast.
One of them “Avast cleanup” is marqued for authomatic renovation and I want to change it to “manual”. But I do not find the way for doing that in my registered area at Avast site.
I do not find any chat for online assistency either. It used to exist one in the past.
Is this the way Avast helps to their customers? >:(
