Oh my goodness did you ever think you would see the day? A day were you can disable iksar and froglok and vah shir and beastlord and berkeeker, or any combination thereof? Well thanks to the open source hero GRUMPY; you now can. Add into your rule_values database table World:UseClientBasedExpansionSettings and set it to false. Make sure in the left column to add a 1 (making that the default rule). Now change the value of World:ExpansionSettings to pick your expansion! Ones already tried are 0-classic, 1-kunark, 255 everything. Test more to figure out if it is just the straight up expansion number no formula needed.
Lets all thank grumpy here is his post!

Try this out, a list posted by Grumpy:
0 - classic
1 - ruins of kunark
2 - scars of velious
4 - shadows of luclin
8 - planes of power
16 - legacy of ykesha
32 - lost dungeons of norrath
64 - gates of discord
128 - omens of war
256 - dragons of norrath
512 - depths of darkhallow
1024 - prophecy of ro
2048 - serpent's spine

Add the numbers up to give you the expansion you want.
0 + 1 + 2 + 8 + 16 + 32 + 64 = 123 (For GoD)
