RBK852: WAN Bonding with 4G Modem

Review the LM1200 spec sheet or user manual to see if it supports WAN LAG. 

WAN LAG requires the use of a signal modem device that has two WAN ports that supports LAG.

I'm planing to buy an Orbi RBK852 Mesh Wifi 6 one of the things that is taking me interest on this specific model is the Mesh and WAN Aggregation

 

So my question before I buy is the following
I plan using this with multiple 4G modems to achive WAN bonding, from the help page I can see that the RBK852 supports this function but the modem must also support Link Aggregation Control Protocol (LACP)

 

So is it possible to use multiple 4G Modems that have LACP support to use the WAN Aggregation?
If so can somone tell me if the NETGEAR LM1200 has LACP support (I can't find a reference anywhere) and if not some recommendations on brands that manufacture modems with this support

 

Thank you in advance
