Stop email notifications for one email account

[AC Question]

I'm new to android, just got a S8 and I'm having trouble with my email. I have my @Live.com account which I use for my calendar only. I also give that email address for junk email. Then I have my gmail account that I use for my legit email. I have set the gmail account as default account, disabled the sync, notifications and sounds for the @Live account but it still shows the number on the email app logo, like I have unread emails. I only want to see that for the gmail account, but I don't want to delete the @Live account because I need it for my calendar.

Is this a built in feature? With TeslaUnread for Nova Launcher this can be done for Gmail (not sure about 3rd party accounts).
