please help..

I am trying to do a test print at costco at 20x30 Lightroom allow me to change the resolution of my images from 72ppi to 300ppi which is how i want them but still maintain the image original dimension which is 5184x3456, is it ok to leave it at the original dimension ( 5184x3456 ) with 300ppi or do i have to upm the dimension which it would be at 9000x6000 for a 20x30 at 300ppi that's how photoshop does it but not lightroom, hope u can understand my question.

if not what would be the best ppi for a 20x30 print and do i keep the original dimension?
