By default with the setting of 5 in 2009 it wasn't.
Seems to be working with the setting of 2 though?
Not sure if it was the drawing I worked with though so I need to do some more testing.

Issues all prompts normally.
1
Suppresses “About to regen, proceed?” and “Really want to turn the current layer off?” (-LAYER)
2
Suppresses the preceding prompts and “Block already defined. Redefine it?” (-BLOCK) and “A drawing with this name already exists. Overwrite it?” (SAVE or WBLOCK).
3
Suppresses the preceding prompts and those issued by the LINETYPE command prompt (-LINETYPE) if you try to load a linetype that's already loaded or create a new linetype in a file that already defines that linetype.
4
Suppresses the preceding prompts and those issued by UCS Save and VPORTS Save if the name you supply already exists.
5
Suppresses the prompt, “That name is already in Use, redefine it?” issued by the -DIMSTYLE Save option when you supply the name of an existing dimension style.
Suppresses the same prompt issued by the -SCALELISTEDIT Add option.
I was looking to do something more elaborate like trying to have it read every block definition file against a specific folder but after going through the possible damage it could do with regard to attribute text alignments etc... I decided against it.
