Edit map settings using script

[Sora]

hello , is it possible to change map settings ( which is in meta.xml file ) using the script

for example when any map starts the script change the setting respawn from "timelimit" to "none"

before using the script

name="#respawn" value='[ "timelimit" ]'>>

after using the script

name="#respawn" value='[ "none" ]'>>
