You’d be better off with a desk topper combined with a standing monitor arm setup. Something like this: https://www.amazon.com/Simple-Trending-Monitor-Anti-Slip-Computer/dp/B07ZSX2DQL/ref=mp_s_a_1_16?dchild=1&keywords=desk+topper&qid=1627161976&sr=8-16. But with the space your provided, I wouldn’t go more than 2 monitors and just deal with the stands or get a desktop combo duel monitor arm with a stand: https://www.amazon.com/HUANUO-Dual-Monitor-Stand-Adjustable/dp/B08DJ5ZRRK/ref=mp_s_a_1_8?dchild=1&keywords=huanuo+dual+monitor+stand&qid=1627162146&sprefix=huan&sr=8-8.
Take it from someone with 12 years in IT, you’re not going to be able to use the 3 monitor setup well with the small space provided unless you go really small.
