I have a list and it has over 5000 items, and when I go to the list settings, I go to turn attachments OFF (disable) I click OK and I get the error:
The attempted operation is prohibited because it exceeds the list view threshold.
Is there no way to turn attachments off? There are no attachments, the user just wants to have the item hidden in the newform.aspx

I tried to "reproduce" the same behavior by creating a large list (5100 items) through script, in both modern and classic team site. But even there, I was able to disable attachments afterwards.
Did you try to handle the settings through PowerShell / CSOM?
A (maybe huge?) solution could be to create a second list using the "from an existing list" option, move items from the first list to the second using PowerShell / CSOM / Power Automate to be under 5000 items, disable list attachments and move back items.
