How do I bulk uncheck "This is a physical product"?

[lazychicken]

How do I bulk uncheck "This is a physical product" for all 1700+ products in my store? This store is for a non-profit and is very specific in nature, so no shipping will take place. We aren't actually selling anything. Just using the platform to 2020 virtualize our annual Christmas gift program that is traditionally done in person.

Apparently the only way to deactivate the shipping options at the end is to uncheck this box. Trying to simplify the check out process as much as possible.

Try to change this column in CSV Variant Grams  As "0"

Vikash4 - I appreciate the reply! I had it set that way during the import and it did not uncheck the box. I am open to any additional ideas.
