Options[image]

This gives a list:

{ColorSpace -> 
   ColorProfileData[ ...], Interleaving -> True, MetaInformation -> {"Something"}}

I can update the values like:

Image[image, MetaInformation-> {"updated value"->"something"}]

The question is how can I prevent MetaInformation from being displayed by Options under some condition?

MMA seems to treat images as atoms, so pattern matching inside an Image object appears difficult. How about splitting the image into data, type and options and replacing your option according to some rule:

ClearAll[replaceImageOptions];
replaceImageOptions[image_, rule_] := Module[{type, data, opts},
    type = ImageType[image];
    data = ImageData[image, type];
    opts = Options[image];
    Image[data, type, opts /. rule]
];

image = Import["https://upload.wikimedia.org/wikipedia/commons/c/c2/Amanita_muscaria_%28fly_agaric%29.JPG"];

image2 = replaceImageOptions[image, (MetaInformation -> _) -> Nothing];

Options[image]
(* {ColorSpace -> "RGB", Interleaving -> True, MetaInformation -> ... } *)

Options[image2]
(* {ColorSpace -> "RGB", Interleaving -> True} *)

EDIT: In case you're just interested in suppressing MetaInformation from the output of Options and don't want to change anything in the image object, you could simply use

Options[image] /. (MetaInformation -> _) -> Nothing
