Aside from Kit's question, the following code will show what the
difference is.
sysuse auto, clear
xi, noomit: reg mpg i.rep78, nocons
xi: reg mpg i.rep78, nocons
Contrary to your experience with -dv-, whatever that is, the second
statement *does* drop a dummy.

Both the following regressions yield no-constant results without
dropping any dummies, but the p values are different for some of the
dummy variables:
xi, noomit: dv iv i.dummies, nocon
xi: dv iv i.dummies, nocon
But what is the -dv- command? -findit dv- finds naught.
