Can I switch from carrying inventory to non-inventory?

Handing over a business which has operated at a multi-member llc to one of the members, who will operate as a single member llc.

We've filed as having inventory for the past 10 years, and have maintained inventory in QuickBooks, but he would prefer to not deal with actual inventory.

Is there a way to change this on our 2020 business return (1065)?
