Only if you get scanned as soon as you land, don't stop and die.
I have watched his vids as well. What might not be clear is the time and activities required before looking for the person with the level 3 clearance.
Sketch the settlement layout.
Identify all buildings and their doors.
Locate charging points and battery stashes (outside ones preferably)
Locate terminals.
Identify guard patrol routes in the vicinity of doorways, terminals, charging points and battery stashes
Consider taking out guards who may present a danger to your activities once you have a cloned ID on you.
Take care on roof tops. I have encountered NPCs having a break on the roof of the building where the level 3 guy I wanted to scan was. He obliged by going to the roof!
Once the item is located, consider ditching the cloned ID as it might be possible to cut you way in to the target building. Once in and you kill the occupants, if necessary you can clone their ids.
Noise suppressed weapons a must. Quieter footsteps may help (neither of my suits have this mod).
And to conclude in the vein of the topic; it is very likely that the guards and workers will at some point be donating materials in the form of kinetic, laser and plasma rounds. Get your shield up quick and run. Very fast. Otherwise you will receive some unwanted materials.

This is... way more complicated than you need, it's more fun this way for sure though.
There's no need to sketch a layout - you can see the layout on the way down in your ship.
Identifying buildings can mostly be done from your ship coming in to land as well - CMD buildings always have a Radar dish on top, and power buildings have a unique shape -those are the most important buildings. Most of the time the alarm is in there. Doors... are pretty easy to find, generally they point into the settlement, sometimes there's and outside door, pretty easy to wander round, or just do a quick look again in the ship as you come down and spot a way in.
Don't really need to identify chargin points and battery stashes, maverick suits carry two batteries, and the charging points show on your mini map, there's normally plenty to keep charged as you move about.
You only need on terminal, you'll probly find one pretty quick, they also show on your mini map.
You don't really need to know the full patrols of guards, just keep an eye on whats close by, and you only really need to make sure that first entrance to the alarm building isn't spotted. You don't need to consider any guards that might present a danger, generally you can just let them start scanning then shoot them in the face while they have no shields. If you get into actual trouble you probly did something a bit silly, but just kill them, you should have the alarm off by now anyway.
Don't bother scanning guys through windows, much easier to scan their corpse on the floor.
E-breach or cut the door you need to get to the alarm console.
Noise suppression is excellent yes. Without noise suppression, you wanna use your elecro zapper to kill the guy in the alarm console room, but it's pretty much the same.
That's a huge list though.
All you really need is a noise suppressed kinetic weapon, and to either spot the right building with the alarm console from your landing, or e-breach a terminal outside to locate it.
Just get to it, kill the person near it, and either e-breach the console or clone the guy you just killed.
It's very simple.
