WIFI Calling Preferences Being Forced to Cellular Preferred

I know this is an old issue, and I have also been seeking a solution for a LONG time, but I have cautious optimism that I may have discovered a solution. Samsung includes a "feature" called "Intelligent Wi-Fi" through its "Knox Ecosystem" that, apparently, attempts to adjust its phones to optimize data usage through the application of artificial intelligence to monitor user behavior over a period of time after which settings are automatically modified, including the prioritization of either wifi or cellular data for handling calls and/or texts. I recently noticed a notification on my handset informing me that it had automatically switched my wifi calling setting from wifi preferred to cellular preferred. For some reason, this prompted me to go to my actual wifi settings rather than my wifi calling settings, after which I tapped the 3-dots icon in the upper right corner and selected "Advanced" Wi-Fi settings. There I discovered a category called "Intelligent Wi-Fi" with a setting called "Switch to mobile data" turned ON, and that contained an explanation saying "Use mobile data whenever your Wi-Fi internet connection is slow or unstable." A little research revealed this article on Samsung's website: https://docs.samsungknox.com/admin/knox-platform-for-enterprise/kbas/kba-360034073174.htm, where I learned that Samsung had experienced problems in the past with users having their phones switched to cellular data against their wishes, causing them to update the software in the manner described in the article. This inspired me to turn the "Switch to mobile data" setting OFF, after which I have now gone several days without experiencing the dreaded automatic switching back to "Cellular preferred" on my Wi-Fi Calling feature. Not enough time has gone by for me to feel completely confident that this issue is resolved, but I am cautiously optimistic. We shall see.
