See the docstring of `org-emphasis-regexp-components':
,----
| Components used to build the regular expression for emphasis.
| This is a list with five entries. Terminology: In an emphasis string
| like " *strong word* ", we call the initial space PREMATCH, the final
| space POSTMATCH, the stars MARKERS, "s" and "d" are BORDER characters
| and "trong wor" is the body. The different components in this variable
| specify what is allowed/forbidden in each part:
|
| pre Chars allowed as prematch. Beginning of line will be allowed
too.
| post Chars allowed as postmatch. End of line will be allowed too.
| border The chars *forbidden* as border characters.
| body-regexp A regexp like "." to match a body character. Don't use
| non-shy groups here, and don't allow newline here.
| newline The maximum number of newlines allowed in an emphasis exp.
|
| Use customize to modify this, or restart Emacs after changing it.

In your case, I think you want to prevent =...= to emphasize
(i.e. shadow) the text when the "border" character is `{'.
