Beamer sequential uncover for TOC two columns

I divided TOC into two columns, but I can’t get it to appear sequentially (the lines in both columns appear at the same time).

I saw a solution using the "multicol" package, however with this package there is no way to choose the breaks and I want only the first section on the left and the remaining sections on the right.

documentclass[aspectratio=169]{beamer}
usepackage[brazil]{babel}
usepackage[utf8]{inputenc}
usepackage{caption}
usepackage{subcaption}
usepackage[abnt-emphasize=bf,alf]{abntex2cite}
usepackage{graphicx,hyperref,url}
usepackage{color}
usepackage{tikz}  
usepackage{multicol}
usepackage{etoolbox}

setbeamertemplate{section in toc}[sections numbered]
setbeamertemplate{navigation symbols}{}
%setbeamertemplate{subsection in toc}[subsections numbered]
%setbeamertemplate{section in toc}[ball numbered]
%setbeamertemplate{subsection in toc}[ball unnumbered]
setbeamertemplate{itemize items}[square]
setbeamertemplate{section in toc}[square]
setbeamerfont{frametitle}{size=huge}

Another problem is with the use of the frame title. I would like it to be left aligned (with the first column). Originally this frame had a sidebar, I removed it, but the frame still uses the space of the sidebar as if it existed. I used the hspace command to shift the text a little to the left. The column text moves, but the frame title does not.
