How to ignore bad boxes with ieeecolor?

Question

I am using ieeecolor.cls for the first time - get it from https://www.embs.org/tmi/authors-instructions/, namely, https://www.embs.org/wp-content/uploads/2020/04/TMI-Template-LaTeX-2020.zip

What annoys me is that the default settings as recommended by the journal result in overfull and underfull boxes:

Overfull \hbox (109.0pt too wide) has occurred while \output is active
Overfull \hbox (162.0pt too wide) has occurred while \output is active
Underfull \hbox (badness 10000) has occurred while \output is active
Overfull \vbox (21.77283pt too high) has occurred while \output is active []

I have tried to fix them, but I don't really see where any maximum width is defined, so I have no idea why any of the elements in the header exceed these widths. Clearly, they do not exceed the standard page margins by 160 points. Then I have tried to suppress them, without luck.

What else can I try?

\vfuzz=\maxdimen
\hfuzz=\maxdimen
\hbadness=100000
\vbadness=100000

Based in part on @DavidCarlisle's comment, this answer works for me in the preamble. This has three parts: the first turns off most box warnings on the page where \maketitle is issued. The next block sets the box warning values back to the previous values at the end of the page where \maketitle is issued.

The third block is only required for the journal option, I believe. It replaces a \vbox from the head code by \parbox[c][15pt][c], maintaining all spacing and still removing the

Overfull \vbox (5.0pt too high)

warnings on later pages.

This full MWE demonstrates the effect of suppressing warning, and generates test warnings which show that warnings are suppressed only on the title page:
