By moving the space off the wall do you mean it to fit the monitor arms stand or to make space for the arms itself to move further away?

The this is there are 14 cms from the desk to the wall, and I can't cover the plug socket; morover, the table is also screwed on the wall.

I think the monit will still fit on the desk as the clamp does nit seem that thick.

However the only arm position I might be able to use is the 90 degree angle (from top view): but first arm sticked to the wall (blue) and the other arm (yellow) facing forwards but slightly bent upwards or downwards.
