Tap your user icon in the upper right corner and choose Preferences. There you will find a section called "Messages from Apple" where you can turn off communication from this support site for posts you have participated in or followed. This is a global setting to turn off all communications.
If there is one particular thread you want to stop receiving notifications from, you just need to unselect the "Bell" icon under the original post of that thread.
It does appear you are following the "IPhone" forum, so if you want to stop receiving notifications from posts made to just that forum and keep your others, then use this link and you will see that you are "Following" that forum and it will have a checkmark next to it. Just tap that button and it will remove the checkmark and you will no longer receive notifications when a user creates a post or replies to the forum.
