How to I get rover to make me unavailable after a booking is confirmed?

I have my settings to where I will board 3 dogs for the night and one dog during the daytime. I also have it set to where I will only accept one client at a time. My question is, how do I get rover to set me as unavailable once I accept a booking? I have a booking coming up where when she confirmed it, it kept me as available and I kept getting requests that I had to decline, will this hurt my search results?

P.S. I looked for flexible availability as noted by some of the google results but could not find this setting anywhere.
