Tracking User Time on Landing Pages Without Page Exit Events

Hello everyone! I need help with a topic: I need to identify the time a user spends on our landing pages. I saw in this article https://muffaddal-qutbuddin.medium.com/track-average-time-on-page-in-mixpanel-c80cbb52be99 that we can use the mixpanel.time_event method, but I have a question: Can I do this without necessarily triggering the page exit event? I ask because I don't want to generate another high-volume event.
