Is there a way to get more rows without upgrading to Enterprise? Is there an Enterprise Lite?

Hello, Airtable fam!

We have reached our 50,000-row max and need 100,000 for our dataset for a grant-funded research project. Is there any way to get more rows without upgrading to the Enterprise plan? We do not need any other features that come with Enterprise, and as a nonprofit, we can not afford the plan. We just need more rows. Is there an "Enterprise Lite" plan?

Thanks all!
