How do I increase RAM usage of brave browser?

I never cared about RAM usage of my browser, so chrome was working fine for me but I also wanted to block unwanted ads or pop-ups. That’s the reason I switched to Brave but now I am encountering a problem, due to less usage of RAM(which was supposed to be a feature of using Brave) it feels like it’s much slower than chrome. Opera GX just introduced a feature to limit RAM or CPU usage, I can easily shift to Opera GX and use some add blocker extension but I want to keep using brave because it’s so much better than any adblocker. So, I wish there was a feature in Brave that gives the user access to manage(increase/decrease) RAM usage by the browser.
