Yes, I have read that the 4a has the Titan M chip. I was interested in seeing that confirmed or referenced somewhere in the Android 11 interface, perhaps in about phone etc. I am surprised it can't be verified.
I don't see other hardware details, e.g. CPU model in my Pixel 3 Settings. It may be that details like that are not exposed in the UI (User Interface). If a terminal app were used and a command like "lshw" were run then the output may/may not provide any obvious details for Titan M hardware. I'm assuming that the command could be run as a non-root user.
