Looks like you missunderstand about note 11 pro 5G codename, especially for global variant (veux) for your comparison with note 11 pro, and i can't found any specifications about note 11 pro 5G pissarro. I think note 11 pro 5G with codename pissarro only sold in china.
Yes, first I linked that comparison based on the wrong information at the other page about the code names, that I also linked.
But, last I said "It seems that Redmi Note 11 Pro Chinese has similar specs than your device, so if you found some development for it, potentially, it could work" because this is the Chinese version of Xiaomi 11i"
Resuming, it doesn't exist a Redmi Note 11 Pro 5G, Chinese version, called officially this way, like it is bad/wrong referenced on the page I based, but, according to most of the sites I found, the code-name Pissarro, apart that the Xiaomi 11i, corresponds to the Redmi Note 11 Pro Chinese (that is 5G capable) https://www.gsmarena.com/xiaomi_redmi_note_11_pro_(china)-11159.php
Redmi Note 11 Pro code named Pissarro is just called as it is, without the appendix 5G.
