Layouts and prototypes

I am making a layout of 170x116 cm CMYK, the print site says that dpi 360-540 is needed, but the layout starts to weigh more than 1GB and the computer cannot withstand this. Is it possible to make less than 100 dpi and will it greatly affect the quality?
Or maybe in some other way to reduce the weight of the layout?

Can. For this size it is acceptable. There is an opinion that dpi should be set so that the document size is around 350 mb. The quality will be proportionally affected, but for example, no one will consider a two-meter banner from a distance of 15-20 cm.

you confuse dpi and ppi
CMYK you don't need

Preferably 300 dpi for printing

Depends on where the poster will hang. Interior or street? Often, for printing with a quality of 720 dpi, the file resolution is 180 dpi, and for printing with a quality of 1440 dpi, the file resolution is 360 dpi. Much depends on the size of the canvas. For images larger than 3 sq.m, 150 dpi is perfectly enough. When saving, choose TIFF and zip compression (you can check with the printing house about compression, since not everyone accepts zip).
