Routing to LACP interface Cisco

We have 2 ISP providing us with internet access. One of them uses LACP to do the load balancing on their interface. They use Port-channel 1 in routed mode to connect to our LACP interfaces and they assigned an IP to get the connection stablished. We have our GiEthe interfaces with lacp on layer 2 (switchport) mode. Is there a way to do the switch of our interfaces into routed mode withour having to take down the LACP switchport interfaces? We tested first to take switchport out to assign and IP on the Port-channel but took the interface down. We were thinking also on creating a new routed more port-channel 2.

Thanks, here is a copy of the LACP interfaces and the PORT-CHANNEL1 interfaces

What model switch do you have?

You're probably going to drop the connection for a few seconds no matter what you do, but it should end up looking something like this:

interface GigabitEthernet1/3
description - MM Fiber 1Gb port in LACP config
channel-group X
mode active
no switchport

interface GigabitEthernet1/4
description - MM Fiber 1Gb port in LACP config
channel-group X
mode active
no switchport

interface Port-channelX
