You can't really do that. If you think of this in terms of the control over the virus being a Proportion-Integral-Derivative type system, then given how long it takes to gather more information about the current infection level in the populace you're either going to overshoot after the corner(too little pressure applied) or undershoot(too much pressure applied) after the corner. You can't apply perfect control to this kind of system such that the corner is perfectly square. Especially where our knowledge is imperfect and subject to a lot of latency, we have to accept that we have very little actual control over how quickly the curve speeds or slows. Thus the bell-shaped curves.
