How to turn off offering to turn on Google Assistant?

I know how to turn off google assistant. But many times when I make some move at the bottom of phone screen it show me the dialog to turn on Google Assistant. I do not want to turn in Google assistant. Never ever. I do not want to see that screen asking me if I want to turn on Google assistant on my phone. Is there a way how to stop that?

In Settings, select Apps and notifications. Click Google Assistant, then click Disable.
