What is my best option to get Thread Border Router?

Hi,
I run HA on RPi 4 and I have some ZigBee devices connected to my Somfy Tahoma Box.

I want to add Aqara U200 over Matter but I need Thread Border Router.
As far as I found the Tahoma doesn’t support Thread.

Is my best option to get SLZB-07mg24 or something similar?

Thanks.
