Is Multipremoves allowed on Lichess?

Are multi-premoves allowed on lichess, such as legal extensions to give ability for multiple premove? MOD- pls let me know!

no, only in correspondence games can you do multi conditioned premoves

Ive heard of extensions which i have seen players use, even on streams, and i want to make sure if that is allowed, and whether or not we can use it,

Not in live chess
