Is there a way to install cuda10.0 on jetson xavier without using the sdk manager?

Hi.
I purchased the retail version of jetson xavier and set it up according to the instructions, but I did not get cuda 10.0.
This is the product page.

This is the procedure.

Is it possible to install jetpack 4.2.2 as it is and only install cuda 10.0 later?
Thanks!
