Technically on-the-fly is possible but it's not really about what the IC is capable of but the possible VID combinations in the table and the exact order the switches MUST be flicked to prevent unwanted VID-code changes. It's not that simple as to just flick them according from VID=1.15V to VID=whatever without paying attention to how the VID code is changed by each flick of the switch... There's a 400 nanosecond time window during which the switches must in the intended position, or else the VID currently set is applied. So one has to follow an exact - often multi-staged - path from a given voltage to another so that VID-code related drops & spikes are avoided. One wrong move and *whoops!* -> 0.7500V -> reset.
