I found 4 carrier boards from other makers that support Jetson Orin Nano and have CAN bus and at least 4 M.2 slots. One is from CamThink and three are from Auvidea.
For reference, your DSBOARD-ORNX supports Orin Nano and has 1 CAN port and 4 M.2 slots (E-key, B-key, M-key, M-key). forecr.ioforecr.io ↗“io.m2_slots=E-key, B-key, M-key, M-key”

| Board | Maker | CAN ports | M.2 slots | Supported Orin Nano / NX |
|---|---|---|---|---|

| JNX46 | Auvidea | 1 | 5: B-key 3042/3052, E-key 2230, E-key 2242, 2× M-key 2280 | Orin Nano, Orin NX (also Xavier NX) |
| JNX45 | Auvidea | 1 | 4: B-key 3042/3052, E-key 2230, 2× M-key 2280 | Orin Nano, Orin NX (also Xavier NX, Nano, TX2 NX) |

A few differences to note:
- NG4500-CB01 is sold as the board only. The module, cooling and storage are sold separately. camthink.aicamthink.ai ↗“Module, cooling and storage sold separately.”
- JNX410 has no slot for Wi-Fi or a cellular modem. All 13 of its M.2 slots are M-key, behind a 13-port PCIe switch. It needs a 24 V supply (100–200 W). auvidea.eu +1auvidea.eu ↗“twelve M.2 key M slots via a 13-port PCIe switch”auvidea.eu ↗“Power requirements 24V (100-200W)”
Same maker: Forecr's own RAIBOARD-ORNX also meets all three requirements. It has 2 CAN ports and 4 M.2 slots. forecr.ioforecr.io ↗“io.m2_slot_count=4, io.can_port_count=2”
May also qualify: these boards don't fail any of your requirements, but I couldn't confirm all of them for each board: Y-C6, DesignCore NVIDIA Jetson Orin Nano 8-Camera GMSL2 Carrier Board, JNX42, Haipob CNF-500 Series.
