I will not say that it is impossible at the moment. It is certainly not documented. You just might be able to change it using one of the hidden properties of the legend. Perhaps one of the ColorSpace properties. Nothing I have tried has worked yet.

In undocumented Matlab, you will find how to do it here: http://undocumentedmatlab.com/blog/transparent-legend.

This solution seems to work in Matlab 2020 +
h_leg.BoxFace.ColorType='truecoloralpha';
h_leg.BoxFace.ColorData=uint8(255*[1 1 1 0.75]');
where h_leg is your legend box handle.

You can refer to the link given below on how to set the different properties of legend
To change the background color of the legend you can change the 'Color' field to achieve the required transparency.

Starting in R2024a, legend supports the ability to control the level of transparency with the BackgroundAlpha property. Below is a short example:
plot(magic(7));
grid on;
set(gca, 'Color', [.88 .88 .88]);
l = legend(BackgroundAlpha=.7);
Setting the value to 0 will make it fully transparent and a value 1 of will make it fully opaque which is the default behavior.
