Can you overflow toilet with one flush if clogged?

With traditional flow toilet, can you overflow it with one flush if it was 100% clogged, or is the tank + toilet designed to never overflow in one flush?

It can overflow, especially since there's always some water in the bowl before you flush.

I don't believe they are designed to not overflow if clogged.

I know the old 3 1/2 gallon tanks could overflow I'm not sure about the new 1.6 gallon although it might depend on the pre flush level in the bowl.

Flushing a toilet to clear a clog will usually not work and there is a likelihood that it will overflow.

MY go-to for a clog (especially if mostly paper) is a 5 gallon bucket. You can pour a large volume of water directly onto the clog and the pressure might be enough force it down. If not then you can always stop pouring before it overflows.

Another trick for a more solid clog is to pour about a cup of dishwashing liquid into the bowl and let it sit. The grease cutting enzymes will work their magic and may soften the clog enough clear it (with the bucket).

My sisters toilet has a flush valve that I've never seen before.
It flushes like a normal toiler but you can pull the handle up and it stops flushing.

It actually makes perfect sense.
Hers is just starting to leak so I'll need to find it.

I remember seeing that at some point but I don't recall how it was done. I'm going to guess that instead of a lift chain the flapper probably has a connecting rod. The flapper design would need to offset the weight of the rod and handle lever so the flapper would stay open long enough to allow sufficient flow before closing in normal operation.

The flush arm goes thru a clip mounted on the flush float.
I tried to find it and haven't yet.
