Yep! Just go to Plugins\Elite Battle DX\[000] Scripts\Battle Modifiers\Scripted Battles, then:
comment out/delete this line in pbShowOpponent and pbHideOpponent:
moveEntireScene(x, (speech ? +2 : -1), true, true) if i%k > 0 || k == 1
the copy and paste this over the bottom of pbShowOpponent...
New to essentials and EBSX, and this is not the exact same solution but this works as long as you have your monitor set to the same refresh rate the game reads in (mine runs it at 240 fps and it adjusts the battles to the correct speed).
The wait function to change is in \Plugins\Elite Battle...
