It appears you're encountering a challenge with Microsoft Dynamics 365 here is version 22.3.58346.58475 where there isn't a straightforward method to allow users to open Excel files without granting them editing permissions. You've tested the "EDIT IN EXCEL - VIEW" permission set, but it seems to only offer an all-or-nothing solution, providing both open and edit permissions or none at all.
You've come across a forum thread that suggests the "EXCEL EXPORT ACTION" permission set might be suitable, but upon testing, you've found that it also includes the "EDIT IN EXCEL - VIEW" set, thus not meeting your requirements.
