You can use this script to disable all addons.

#! /bin/sh
addon=$(vela addon list|grep enabled|awk {'print $1'})

fluxcd=false
for var in ${addon[*]}
do
  if [ $var == "fluxcd" ]; then
      fluxcd=true
      continue
      else
        vela addon disable $var
  fi
done
if [ $fluxcd ]; then
    vela addon disable fluxcd
fi
