Out of interest, why don’t you want to use a three position switch

Sorry I’m only apprentice, I just want to know the different ways as we came up to a job this week where the customer wanted something similar

There's 3 ways to do it.

Switch on the permanent live. This means the light can be turned fully off. Turning on the switch supplies power to the sensor, which in turn turns on the light when it detects something.
Common when you are replacing an existing light with a sensor version.

Over ride switch. Power is always on to the sensor - meaning it will work when it detects something, and will never be able to be switched off.

Combination of both of these. So the light can be always OFF, always ON, or sensor controlled. This can be done by a 3 position switch, or a combination of 2 x 1 way switches as per your diagrams.

It is the specification of the customer or the job in hand, so there is no right or wrong way out of those 3 options.

Also, there are some sensors that operate an override if you flick the switch on-off-on within a second.

Thanks for your help I just wanted to know different ways of how to manual override a pir
So I’ve found 1 gang

Thanks that’s all I wanted, I will do some diagrams in a bit of these 3 methods so I can always have it and remember how it’s done
