Possible to disable alliances?

[J-Plague]

If it's possible, how would I do this? I want ceasefires to still be possible, just not alliances.

Spoiler Alert, click show to read: 

<item name="offer_alliance">
<cost modifier="1.0"/>
<faction_standing modifier="0.25"/>
<global_standing modifier="0.5"/>
</item>

Setting that to 0 should make it impossible for the AI to ask for an alliance.

Edit: Forgot to mention, that's in descr_diplomacy

Seems to be working, thanks
edit: nevermind :| they still ally. It's rather rarer now though.

Hmm, well try setting it to a negative value then. Maybe -10.
