Make stairs that don't require a handrail
Yes, 4 or fewer risers do not require a handrail. (See ICC R311.7.7) and must be 36” wide minimum. 

Risers cannot exceed 8” and treads cannot be less than 9”. (See ICC R311.7.4)

Also, the largest riser cannot be more than 3/8” different than the smallest in the same run. (See ICC R311.7.41)

There has been some discussion in the past (between Building Officials) as to whether or not a landscape stair must comply with the Building Code. The Code defines a “stairway” as “either interior or exterior” but goes on to say “within or attached to a building, porch or deck”. (See ICC R202.1)

Likewise, steep sidewalks do not need to meet the requirements of ramps with handrails, landings, etc. 

I think you can do what you want (or feel comfortable doing), but you might ask your local Building Department.
