"slim" code base for PN7360 application?

I am developing a relatively simple NFC application, using the PN7462 family with NTAG 424 DNA PICC's. It is for an application where a product will have attachments sold separately, and we wish to employ the secure framework of the NTAG to reduce the possibility of other companies providing attachments to our product, sort of an anti-counterfeiting approach. We will embed the NTAG in our attachments.

It will be a simple use case of the PN7462, using the secure authentication to basically allow our product to operate.

We want to use the PN7360 for cost reasons as we don't need the contact feature of the PN7462. I have the NXP OM27462CDKP development board and have the phExMain running on it and working. I will not be able to use this framework as it is too bloated with everything the PN7462 features have, will all the available NFC devices and compiles to 143K, thus won't fit on the 7360.

I simply only need the following:

1. CLIF only, no CT functionality
2. No RTOS, don't need it, just want a simple embedded loop program structure
3. Only the code needed to read/authenticate the NTAG chip, nothing else

Does NXP have any SW resources, code examples, for what I am trying to do? I noticed there is a C file entitled NoRTOS, which I assume is intended to build simply loop programs without the RTOS? However, I cannot find any documentation.

I will need to add the code for the NTAG authentication, but for now want to get our prototypes working to simply detect the NTAG.

I would think there would be quite a number of people wanting a simple embedded application like this, so I am surprised I cannot find any examples of code to help me get going. Can anyone assist?
