How would you enable the count and disable the load on a 74190 chip?

Have you read the datasheet?

Please make thread titles more meaningful. "Homework help" is a bit vague and rather redundant considering that this is the Homework Help section of the forum.
I have edited the thread title for you.

Thanks, I've tried that, but I am unclear on how to enable the count

When the part is counting:
Load is high, CTEN is low.
