Sixty INDIVIDUALLY on/off switchable COB LEDs connected in parallel: how to drive?
As the others said you will need a constant voltage power supply of 12-14V (your choice) capable of outputting enough current, which depends on how many LEDs you want to light at the same time. Since 12V supplies are quite cheap this shouldn't be a problem.

Note that normally "led drivers" are constant current, this is not what you need here, since the current will depend on the number of LEDs which are ON.

However manufacturers have discovered that when people who want to use "12V LEDs" (which already include a current limiting resistor and need a constant voltage supply) will only buy it if the label says "LED driver".

Confusion is the result. If it has "LED driver" written on the label, now you got to check if it's constant voltage (it will say "12V 3A") or constant current (it will say "3A 8V-18V", indicating the output voltage will adjust inside the range mentioned to keep the current constant). If you're really lucky it will say what it actually is on the label...

Now you will need individual switches to control your LEDs, considering the number, the easiest would be MOSFETs driven by switch registers or i2c IO expanders. You can use SMD dual FETs in SO-8 packages for small size. There are also power shift registers. 

If you want to use PWM at high frequency to avoid blinking, make sure you can clock the shift registers fast enough.
