How to avoid PMI with 10% downpayment?

[Sarp Ka]

Hello I've been reading that you can get a second loan providing that 10%, so that on the title it shows as I paid 20% downpayment hence it's not bound to PMI.

I'm wondering which lenders do that? Do I have to get 2 separate lenders and ask them to do the 10%? Do all lenders agree to be on the side that's providing 80% loan; and the same goes for lenders who want to be on the 10% side?

Thanks
