Can you easily bond two 2.5GbE ports? - eviltoast

I just had fiber installed yesterday and got a 3Gbit plan.

The modem provided by the ISP has 1x 10GbE port and 4x gigabit ports.

I got a 10GbE NIC for my Synology NAS, which is installed right beside my modem.

However my PC is sitting at the opposite end of a 30m+ Cat5 run. The silver lining is there’s a pair of them.

Can I bond them somehow to make them a single 5GbE port?I haven’t bought a switch or router yet.
