Help interfacing STM32H7S3L8 with 24-bit RGB LCD — no LTDC?

I'm trying to configure the STM32H7S3L8 to work with a 24-bit parallel RGB LCD. From what I've read, this kind of interface usually requires either an LTDC peripheral or a dedicated display controller board. However, I can't find any documentation confirming whether the H7S3L8 includes LTDC.

Can anyone confirm if the STM32H7S3L8 supports LTDC? If not, is there any practical way to drive a 24-bit RGB display directly from this chip, such as using the FMC, or do I need to add an external display controller?

Thank you for your help.

I am very new to everything ST related... do you mean literally select every box for boot and app, or look through them to find LTDC? If you mean the latter, I have already done that, and have only found the FMC LCD controller, which I believe will not work on my display. 

Agree seems LTDC isnt present in S3 MX config. Not clear why. And steps is use search on up.

S7 have example for LTDC , then maybe ... , but ST have bugs in systems...

When S3 not have then supported is 8080 displays... but datasheet show pins for LTDC then try use manual config

I searched for the LTDC ...in H7S , and from ds :

So H7S7 has LCD-TFT , H7S3 only FMC 8/16.

-> If 8 bit par interface is not working for your display, because need  24-bit parallel -> H7S7 needed.
