Do all QSFP+ ports require bonding in CRS326-24S+2Q+RM deployment?

As I prepare to deploy two CRS326-24S+2Q+RM switches at work, my intention is to utilize the QSFP+ interfaces in 802.3ad mode to establish a link between the switches. To achieve this, I am wondering whether it is sufficient to add only “qsfpplus1-1” and “qsfpplus2-1” to the bond on both switches, or if I need to include all the QSFP+ ports in the bonding configuration.
