No Thunderbolt - any alternative?

Hello, I really need advice!
I want to buy a reference monitor, but I ran into a problem, I don’t have a Thunderbolt 3 output on my laptop, is there an alternative way to connect my laptop with a reference monitor?
laptop Lenovo Legion Y540-15IRH
monitor BenQ PD2700U

Good afternoon, my situation looks like this. The monitor I bought Benq PD2705 does not support connection to Thunder Bolt 3, and my laptop Lenovo Legion Y540-15IRH does not either. I thought that UtraStudio Monitor 3G was enough for me to connect, but the studio also supports Thunder Bolt 3 connection.
What should I do in this situation what is the best way out and there is a way out of the device based on the USBC?
I use Davinci for color grading.

While you got a pretty good monitor, you have unfortunately bought the wrong laptop. But then, it depends on your target audience if the lack of precise monitoring really matters. If they all watch on smartphones or the like, nobody cares about wrong colours or contrast.
If you work for broadcast, it matters. Sell the laptop, it's only good for HD anyway, and get a strong gaming laptop with Thunderbolt or any MacBook.
