You can set the interval in the .fetchmailrc file. Mine is below:

https://pastebin.com/cjtnjBnY

My main email address is checked every two minutes as shown in this
setting
set daemon 120

The rest of the servers checked are multiples of that such as 
poll imap.gmail.com with proto IMAP port 993 interval 2, so my gmail
account is checked every 4 minutes.

You can also find a lot of info on fetchmail here -
