How could i change the line width at parameters in specific layer (Adobe spatial pdf feature writer ) without effecting lines width at other layers ?

when i change the Default line width to 0.6 in feature wirter ( adobe geospatial pdf in Feature writer ) ,i found it changes for all layers .

i would like to change only for one layer and others still has the same width of lines .

How could i achieve it ?

i need only to change paramter of width of lines in one layer without effecting other lines at other layers .

my workspace : i have different lines ,with different colors

and i would like to increase the width line with green color that i show in pdf output and others still have the same line width in pdf output .

Thanks in advance
