Yes, it is available on the Samsung top-load washers like WA-23A8377GV/FQ: when a wash session begins, the dock lock automatically activates. You can unlock the door by pausing or ending the current wash session. There is also a child lock feature available.
LG top-load washers like TH2722SSAK also have door lock and child lock:

However, you might need to describe your use case if you mean anything else.
My concern is dun wan ppl to open the door when the power is off [meaning it is locked during night time example]
Samsung front load got this Child lock and when you activated it and power off the machine, the front door will lock itself and unable to open.
The LG top load of mine doesnt, it will only locked when you start a cycle to prevent you open the door.
The child lock wont extend till like the samsung does.
So when i power off the machine [with child lock enabled] , i still able to open the top load door
