According to that maintenance schedule, it's 80,000 miles.
However, they have so many different versions/revisions of their maintenance schedules posted with various information, it's kind of hard to confirm which is the most accurate. What we find on various sites is likely outdated/incorrect. If you want the most up-to-date information, pay for a subscription to

Personally, I would not wait 80,000 miles to change spark plugs, even on a stock car. They are not expensive and I'd rather be safe than sorry.
Edit: Actually, it appears erWin is displaying the 11/2019 revision even for 2021 cars... That would lead me to believe yes, 80,000 miles is the most accurate spark plug change interval recommendation provided by Volkswagen for our cars.
Revision 11.2019 is displayed for MY 2018, 2020, 2021
Revision 8.2019 is displayed for MY 2019
80,000 mile spark plug change interval listed on both revisions.
