I have done it on a Chinese version of the Mi10Pro, now running on MIUI 11.2 20.3.28. There are a couple of good videos on youtube that you could google yourself, detailing all the steps needed. In my opinion, the better and less visited articles are in Chinese. If you do not read Chinese, then you like to google with this phrase "小米10pro刷国际rom“. Essentially, it translates into "MI10PRO flash international ROM". EU ROM are there too. Videos shows pictorially all the needed detail steps. Have fun.
