iATKOS Inside: Can I use the WWAN antenna as the 3rd antenna for my wifi card? (Half-mini PCI-E BCM94360HMB)

Can I use the WWAN antenna as the 3rd antenna for my wifi card? (Half-mini PCI-E BCM94360HMB)

...

MacOS 10.14.6 - Opencore 0.6.7 - HP folio 9470m (i5-3437U)
Right now, my wifi card is BCM94352HMB. Wifi/Airdrop works great. Unfortunately, I can't manage to get Handoff/Instant wifi/University Clipboard work.
I am planning to switch to the BCM94360HMB for better feature. The problem is the BCM94360HMB wants 3 antennas, but my laptop only has 2 antennas. I noticed that there are 2 more antennas for the WWAN card (spare). Any change I could use the WWAN antenna as the 3rd antenna for the wifi card? See the photo below for more info 👇

One more question: Dortania's guide said the BCM94360HMB needs some kexts to fully working. However, this Tonymac's guide and few other people said it is natively supported in macOS. Which is correct? Did anyone manage to get Handoff/Instant wifi/University Clipboard work with on this card?

Thank you for reading! 🙏
