No, it is not possible, at least not in the ZHA integration (nor in Zigbee2MQTT), each device in a Zigbee network is meant to handle Zigbee routibg automatically and always just connect via the best link it can find, so solution should simple be to add more Zigbee Router devices. Thus suggest to get more Zigbee Router devices with stronger radios to place closer to those with issues so other devices will automatically connect to the better routes instead, again check out → Zigbee networks: how to guide for avoiding interference and optimize for getting better range + coverage
