plumbing rough-in

For upstairs master bath, the access for double lavs will be only in one place for both 3/4 lines (with 1/2 tee's). The stud wall is non-load bearing, can side by side 1/2 inch holes be used to reach both lavs?
Or do I need to go with one above the other.?
Engineered floor joists prevent another access.
