Let's Encrypt setup issues on CentOS7

I’ve done all the steps.

Disabled root, added frappe user to wheel.
Currently I upgraded to V11.

I havent done the upgrade of pip so far - why is there not the newest build in the setup process?
Do I have to upgrade pip now? Everything is working fine now except ssl and I dont want to start from scratch now - that’s why I want to make sure that this is the next step.

Thanks
