How to Disable Motion Sensor but Keep Twilight Sensor on Philips myGarden 15388/30/16?

Problem: how to switch off the motion sensor but not switch off the twilight sensor.

I want to buy such outdoor wall sconces:

Philips myGarden Wall light 15388/30/16

I bought one for testing, the twilight sensor is adjusted with a knob to optimally set when the lamp should switch on.
the motion sensor unfortunately has an action from 5s to about 5 minutes also adjustable by a knob - I assume it is some kind of resistor.
i would like to somehow bypass the motion sensor (disable it) so that the lamp is switched on at dusk and switched off in the morning and not only at night in case of motion.

How do I go about this?

ps I once had a soldering iron in my hand but by accident

Since you don't want to use a motion sensor, you need to buy a lamp with a twilight sensor (no motion sensor)
Conversions do not always work out.

I want this particular lamp.
I am prepared for the possible failure of the conversion.

I'm going to bury the subject a bit. On the B-net... there are to be led bulbs with motion and dusk sensor. I just need a twilight sensor action (lights up in the evening, goes off in the morning). Is it possible to convert this fairly simply (some jumper, resistor...)?

All I have access to is the socket (an old porcelain from the former Soviet Union with a glass bulb screwed on), but I'm not allowed to do anything there. So all I can do is screw in a suitable bulb, preferably one that looks inconspicuous, as it will be "useful" to someone.
I do have access to a switch for this bulb, but not something that can be fitted instead so that it turns on at night and off during the day?
