Read-only textbox and/or disable buttons in Infopath 2013

Question

In a InfoPath 2013 custom list form, my requirement is to make textboxes read-only, disable buttons, and/or create new buttons so users can not update fields in a custom list once the user has updated data in the list. Basically after the user hits the 'save'
button so that the data is saved.
The requirement is not to set up custom permissions since my SharePoint administrator said I should find another option. This administrator said he does not see a reason for only an 'add' permission.
Thus can you tell me how to meet my requirements? Can you show me screen prints, pictures, or urls on how to solve the problem?

Hi,
According to your description, you might want to prevent users from editing the existing items.
There are two workarounds I can provide as below:
As the first workaround, you can remove Ribbon from SharePoint InfoPath List Form via modifying the OOTB settings of InfoPath Web Part.
Here is a link about more details, you can use it as a reference:

As the second workaround, you can apply the CSS code below to your page, it will hide the “Edit Item” button in the Ribbon:
<style type="text/css">
#Ribbon\.ListItem\.Manage\.EditProperties-Large{display: none !important;}
</style>
