Do all cart that don't have pads change there mirroring at will?
Yes. Even some that do have pads, such as
TFROM, have three sets of pads: "force vertical arrangement", "force horizontal arrangement", and "mapper controlled".

What about an mmc1?
MMC1 is more flexible than a standard MMC3 in mirroring: it can freely switch among vertical mirroring, horizontal mirroring, and AOROM-style single screen mirroring. MMC3 lacks the single screen mode except on boards wired in a
configuration like TLSROM, where the upper CHR ROM bank bit controls mirroring.
