An awk version

awk -F, '{gsub(/\^\^\^/,",");NF-=1}1' OFS="^^^"
something0^^^something1^^^something2

Fixed by changing FS to some else

Another version

awk '{sub(/\^\^\^[^\^]*$/,x)}1' file
something0^^^something1^^^something2

Using pure BASH:

s='something0^^^something1^^^something2^^^something3'
echo "${s/^^^something3/}"
something0^^^something1^^^something2

OR you can just delete everything after last ^^^:

echo "${s%^^^*}"
something0^^^something1^^^something2
