CallbackFS doesn't do any additional actions when it handles the security requests. I.e. when the CallbackFS driver obtains IRP_MJ_QUERY_SECURITY and IRP_MJ_SET_SECURITY it only passes them whithout any modifications to the OnGetFileSecurity and OnSetFileSecurity callbacks.
I don't know why Process Monitor doesn't show some of the security requests in your case, but perhaps some system or third-party code doesn't send these security requests to the top of the file system driver stack but sends them directly to the CallbackFS driver. The other reason is that the originator of these requests is some file system filter driver which is placed between the Process Monitor file system filter and the CallbackFS driver, and sends the requests not to the top of the FS stack but to drivers which are located below.

SecurityInformation == 31 means "everything". I.e.
