Yes, I suggest a VERY early start or a VERY late start.
The White Ranch Open Space has a live-in ranger, so a headlamp is ... noticeable?
Interestingly, the actual summit area is OPEN open space, but the access area to it is CLOSED open space. I have not pursued access through the private property (there is a house VERY close to it at the NE corner of the peak), but it an option. I'm sure they go up there. The access to their property, however, is gated off of 93. Also, there is an open uranium mine (plowed in winter) west of the peak (on the west side of the ridge). I'm sure those folks who live in that area also walk that road (good or bad).
