According to a different article I was just reading, sounds like the 2030 isn’t a hard date and it may be extended if commercial stations aren’t ready to go:

While the 2030 end date has been referenced in NASA budgetary materials in recent years, some NASA officials have stated that the station could potentially remain operational past that date. “There’s nothing magical that happens in 2030,” Steve Stich, manager of NASA"s commercial crew program at Johnson Space Center (JSC) in Houston, said during a Jan. 25, 2024 briefing.

Stich added that the ISS will continue operations until commercial space stations are in orbit and ready for crews. “We want [the commercial stations] to be supportive, and then when they’re ready to go, that’s when ISS will move out of the way,” Stich said.
