I have a picture for you to easily understand

In my working place, there are two type of router, both of them can connect to internet. Router 1 (eno1 interface on Proxmox) is the router that connect between departments and have more strict rule and firewall, the access to this router be controlled by IT Department and each computers must let them access directly or via Remote controller programs like Ultraviewer. The second router (enxXXX interface on Proxmox) is the router installed exclusively for my departments so it will not eat up every bandwidth of router 1 when NIPT finished sequencing and pour data to the contracted database.
The problem is that not every computers connect to enxXXX, its almost used by NIPT workstation and others smartphones via Wifi, the main LAN network on my department is the eno1. Now I'm charging of making temporary cloud storage for department until the IT department deals with the other requests. I can bridge the enxXXX and others computers can access Nextcloud by typing the IP related to that bridge (192.168.5.XX). However, the eno1 router only recognize and turn up IF THE OS IS WIN10. I tried to contact to IT department to map the internet so I can access Proxmox and everyone can access Nextcloud through computers that connect to this network, but they do not familiar with Linux and give up. I also tried pfSense VM with PCI Passthrough entire network port but the moment pfSense turned on the interface immediately shut down and I have to call IT Department again, then received a direct warning to not plug this network to any routers without their permission.
Now I have to create a win10 VM, PCI passthrough network port to this VM and ask them to allow Win10 VM to connect through this network with IP 192.168.7.xx. Is there any way I can make another bridge like vmbr1, link this bridge to the IP of my Windows10 VM so I can access Proxmox and Nextcloud VM on this LAN?
