Grav external requests

I have a question about self-hosted Grav making external requests right starting from login operation.
It probably is a security issue for us that Grav is making getgrav.org :443 requests even when I disabled feeds/notifications etc from admin plugin's admin.yaml configuration.
Is there any way stopping such external requests?

Or if not, then what is the reason (telemetry,..?) behind continuous getgrav.org communication?

All the best!

Is there any reasonable explanation for this?

Ill give you a good example: some 15 minutes ago getgrav.org was down - that actually disabled working with Grav for us.

This issue may direct us to give up using Grav, but it may be, that there is some misunderstanging in our side and it's possible to configure Grav not being dependent on getgrav.org.
