Well a diode doesn't by nature allow current to flow in both directions. So basically if it is working it is going on and off 60 times a second, spending half it's time off. When a diode is blocking the reverse bias heat dissipation would be increased. Likely shortening the life of the diode as well as producing half the light and generating excessive heat.

When forward current is applied there is a little resistance and therefore some heat is generated. When flow is reversed the diode acts as an insulator. Forward voltage drop is increased as temperature increases and therefore blocking the reverse current half the time and creating excessive heat will further degrade performance of the diode during the time voltage is flowing forward.

Honestly it's not something I have ever experimented with for the aforementioned reasons. It's just not how LED's are supposed to be implemented.

So definitely using the DC power supplies I have. Assuming I can figure out how many lights each supply can power by dividing the output watts of the supply by 12 (the watts the lights are advertised to consume) yes? And assuming the answer is yes to that question, I should be able to wire the lights for each supply in series, yes?

Series or parallel connection depends on the output voltage and amperage of the DC power supply that you are using.

Sorry, my explanation was not clear. Assuming I use 10 strips each consuming 12 watts, the power supply should provide 120 watts of power: 10 volts and 12 amps, or 12 volts and 10 amps, or 24 volts and 5 amps, yes? Just trying to ensure my very basic understanding of watts is correct. The other option I may have is to buy a single 300-watt power supply, although the only thing I am finding is power supplies for desktop computers. There must be something out there for use with LED lights although everything I see is labeled as a 'driver' so I am not sure what the difference between a 'driver' and a 'power supply' is?

heres some info to get ya started on drivers...https://www.meanwell-web.com/en-gb/led-drivers/
You still need to find out what voltage the strips use...have you put a meter on them?

So Googleing some #'s printed on the strips I am finding references to direct AC drivers. Here is the first reference document I found: https://www.mouser.com/datasheet/2/149/FL77905-962516.pdf
This and other references I recall lead me to believe these strips were purpose-designed to be used in replacement bulbs for fluorescent fixtures using common household current. Still reading...
