Can I turn off these emails: We've detected a sign-in to your account from a new IP address

I have a mastodon.social account (if the instance I'm on matters). I use VPN and notice I'm getting these emails each time I sign in. My account is also just a post viewing account, so I have no account security concerns.

I checked the settings UI in mastodon and all email preferences are content/interaction-related versus security-related - I couldn't find any way of turning these emails off.

Setting up 2FA to extinguish this is out of the question. Is there a way to turn these emails off on the Mastodon side or are my only options to mark Mastodon emails as spam on the email side (or delete the Mastodon account and go back to viewing without an account)?

TIA! :)
