Hello,
I would like to have three corners rounded as in the figure.
Not sure if you had simplified your example or not. But if all you want is
a rounded corner, you can consider using corner=number parameter of framed
and framed text:

Here is an example (that does not use metapost).
\definecolor[MyColorA][r=0.8784, g=0.8784, b=0.8784]
\definecolor[MyColorB][c=0.00,m=0.27,y=1.00,k=0.00]
\defineornament
[FrameTitle]
[preset=lefttop]
[
frame=off,
foregroundstyle=\bfx,
foregroundcolor=white,
background=color,
backgroundcolor=MyColorB,
]
\defineframedtext
[FramedText]
[
offset=0.6em,
toffset=\lineheight,
background=color,
backgroundcolor=MyColorA,
foregroundstyle={\switchtobodyfont[10pt]},
align=verytolerant,
frame=off,
corner=01,
]
\showframe
\starttext
\FrameTitle{Info}{\startFramedText[width=10cm]
L'équivalent vingt pieds (EVP) est une unité de mesure de conteneurs
(de longueur courante 20 pieds, soit environ \unit{6,1 meter}).
1 EVP représente environ \unit{38,5 cubic meter}.
