I'd wager it's these ones that you're looking for:
## (call_script, "script_diplomacy_start_war_between_kingdoms", "fac_kingdom_1", "fac_kingdom_2"),
## (call_script, "script_diplomacy_start_war_between_kingdoms", "fac_kingdom_1", "fac_kingdom_5"),
## (call_script, "script_diplomacy_start_war_between_kingdoms", "fac_kingdom_4", "fac_kingdom_2"),
## (call_script, "script_diplomacy_start_war_between_kingdoms", "fac_kingdom_4", "fac_kingdom_1"),
## (call_script, "script_diplomacy_start_war_between_kingdoms", "fac_kingdom_3", "fac_kingdom_2"),
## (call_script, "script_diplomacy_start_war_between_kingdoms", "fac_kingdom_3", "fac_kingdom_5"),
just do a search for one of them in module_scripts and remove the ##, and change the faction numbers to your liking, that should do the trick
and after that it's up to you if you want to remove this one to keep the wars static or not:
(try_for_range, ":unused", 0, 70),
(call_script, "script_randomly_start_war_peace", 0),
(try_end),
as for the font, no clue
