The secureRom was deactivated in a later patch. if memory serves correctly, originally you had to have your CD in. After said patch (1.4? or was it with the UBM? ) this was no longer the case.
In other words, yes it did have an active DRM at one point, but it no longer does if you have the latest version. In any event, you don't mess with Uplay at all with SH4.
