New firmware updates do not show up after locale change

Hello, I bought my GNote PRO 12.2 LTE in Hong Kong. Then, moved to Japan in mid-September. I changed the locale to Japanese. Since then, from this forum, it seems that there has been 1 or 2 firmware update. However, I have not received such notification. Even I manually went to settings to check if there is any new firmware update, the device reports that I got the latest firmware. Now I am travelling Hong Kong. Again, after manually checking for possible firmware upgrade, it says no. Have I messed up the system so that no more firmware upgrade is detected? The one I got is:

[Exynos 7884][Verizon] Samsung Galaxy J7 Top 2018 (SM-J737VPP) Custom ROM or at least Root??

I am unable to find a custom ROM or even a root method for the J7 Top 2018 with the model number SM-J737VPP. I have the Verizon Wireless model, and the baseband is J737VPPVZWABUJ3 with the SW Rev being A. I thought I could maybe use a loophole in Samsung Experience by downgrading from Android 9.0 Pie (OneUI 1.1) to Android 8.1.0 (Experience), but I can only find Android 9 ROMS for my baseband and SW Rev, and I don't want to break carrier services or anything. My plan here is to find an AOSP ROM and upgrade to Android 13 (LineageOS 20) or at least 12 (19.0) or probably a Go (edition) equivalent on AOSP. I am also missing OEM unlock in the Dev options and using the date change method, I still can't get it. I've never hacked a device with a Samsung Exynos chip though before. Maybe if this had a MediaTek chip I could at least root the phone.
Current ROM: OneUI 1.1 | Android 9.0 Pie
Current Recovery: Stock | 3e
SW REV: A
Model #: SM-J737VPP
