Changing ifgrp from multimode to multimode_lacp

Hi,

ONTAP 9.1

FAS8020

I currently have an ifgrp running in 'multimode' mode but would like to working with the network team on changing it to 'multimode_lacp.' However, on the NetApp side, I don't see a way to modify. Do I have to delete the ifgrp and recreate with 'multimode_lacp?"

Thanks,
