Import external emails into Gmail only once per day at 8pm

In a Gmail account example@gmail.com, I'd like to import new emails from activity2@gmail.com (or from activity2@hotmail.com) only once per day at 8pm, to avoid being disturbed constantly at any time time of the day with the emails related to this activity.

The feature Settings > Accounts and Import > Check email from other accounts works, but it checks the email too often (once per hour). Is it possible to totally disable automatic hourly check? (Then I could trigger the check for new emails from API, once per day).

How to do this only once per day?

I'm ok to use Google Apps Script, to use an API from my server with a cron, etc.

What simple solutions are there?

Note: here it's precisely the opposite request :) :

• Is there a way to increase the rate at which Gmail fetches mail from another account?

• Can I control how often Gmail polls POP3 accounts for incoming mail?

• How can I increase the frequency Gmail checks other accounts?
