A local x3fw = 3 at the top of the file feeds four cvars, set in ConfigureShard(), ConfigureDediServer(), ConfigureZoneInstance() and advertised in ConfigureLoadBalancer(). One per queue type: PvE, PvP, coop, brawl.

local x3fw = 3  ---- x3 FIRST WIN
-- Experience multiplier for the first PvE win of the day. (type: float)
cvars.sv_dailyWinPveExpRewardCf  = x3fw
-- Experience multiplier for the first PvP win of the day. (type: float)
cvars.sv_dailyWinPvpExpRewardCf  = x3fw
-- Experience multiplier for the first coop win of the day. (type: float)
cvars.sv_dailyWinCoopExpRewardCf = x3fw
-- Experience multiplier for the first brawl win of the day. (type: float)
cvars.sv_dailyWinBrawlExpRewardCf = x3fw
Change the local once (e.g. x3fw = 10) and all four follow. Set to 1 to disable the bonus.
Additional Notes: 

One local drives all four cvars.
