Daz to Blender: how to reduce the number of vertices or heaviness?

Navigator_ITA

Hi. I'm not a pro user and I would like to know if there is a way to reduce the heaviness of imported figures.
I use Daz to blender 3.6 to load the figures and then use them on 4.2.
The problem is that 20GB of used memory is reached too easily. Is there any setting in the plugin that can help me?

Usually it is enough to use simplify to reduce subdivision and textures.

 This can help. Decimate doesn't work of figure, btw unsubdivide help very much and I can decrease all elemente that are not too much close the camera. 

I totally forgot this function, btw thx for help.
