No. The LDraw Directory setting is global (i.e., not connected to a preference set). If you look at the last paragraph of the "Specifying Preferences" section of LDView's help, you will see an explanation of what the "Global?" column in the preference sets list immediately following means. And if you look at the LDrawDir setting in that list, you will see that it is global.
