Tax experts: Please help me with the QBI deduction for rental proprites

Suppose I have three rental properties.

The first two properties generated positive gains in 2020 and the 3rd one had the loss.

Can I put the first two profitable rental properties in one entity/enterprise and apply QBI deduction (199A) on it, and leave 3rd property alone (no QBI deduction)? or I have to put all of  three rental properties in one entity no matter whether each of them is profitable or loss?

 

Thanks.
