Magento 2: selling 0.5 item as MINIMUM quantity with no stock management

I noticed that the 0.5 minimum quantity doesn’t work if the stock management is not activated.
Do you guys know how to make it work having the stock disabled?

Right now it looks like I can still put 0.5, but the problem is that when I try it, it tells me that the minimum is 1. It just ignores it.

Is there a way around it?
Thanks
