International Note 9 Questions...

I have a Note 9 on order from Rogers (Canada), but am interested in the dual-SIM, International Exynos version from eBay. Anyone know if the Exynos version supports Google Pay (one of the ads stated it didn't) or if there are other issues to consider when picking up an international, Exynos edition?
The key motivator for me is the dual-SIM. An unlocked bootloader would be good to have, but not necessary for my needs. Would the dual-SIM Snapdragon version offer any advantages?
N9600 should work in Canada and not the Exynos version due to LTE band support frequency.

Question Flash Korean snapdragon firmware to G998U1 to change available 5G bands

Hello,
can I flash the Korean snapdragon firmware to an American model (G998U1)?
If yes, will this change the available 5G bands to the ones in Korea? Thanks.
Korean model is Exynos this year.
Also, from reading the specs on Samsung Korea's Web site, it only supports N78 & N77 Sub6 bands

Yesterday I tried flashing my U1 with a Taiwanese firmware and it did not succeed. I'm having the same issues with bands. Where I am they are using bands B3 + B20 for carrier aggregation. So right now I am only able to get LTE and not LTE-Advanced. I guess I'm missing some sort of profile? Because the phone does support these bands.

Unlikely, since dark11b said he tried Taiwan and it didn't work.
I think Taiwan & Hong can be cross flashed, but not with American models, for some reason.
