How to allow data:text/javascript?

I want to allow including javascript in data:text/javascript format. I haven’t clicked to disable unsafe-inline. However it gets blocked with the following message. How can I allow it to load?

Refused to load the script ‘data:text/javascript;base64,d2luZG93Ll93cGVtb2ppU2V0dGluZ3M9eyJiYXNlVXJsIjoiaHR0cHM6XC9cL3Mudy5vcmdcL2ltYWdlc1wvY29yZVwvZW1vamlcLzE2LjAuMVwvNzJ4NzJcLyIsImV4dCI6Ii5wbmciLCJzdmdVcmwiOiJodHRwczpcL1wvcy53Lm9yZ1wvaW1hZ2VzXC9jb3JlXC9lbW9qaVwvMTYuMC4xXC9zdmdcLyIsInN2Z0V4dCI6Ii5zdmciLCJzb3VyY2UiOnsiY29uY2F0ZW1vamkiOiJodHRwczpcL1wvZGlyZWN0YWRlbnRhbC5jb21cL3dwLWluY2x1ZGVzXC9qc1wvd3AtZW1vamktcmVsZWFzZS5taW4uanM/dmVyPTYuOC4yIn19OwovKiEgVGhpcyBmaWxlIGlzIGF1dG8tZ2VuZXJhdGVkICovCiFmdW5jdGlvbihzLG4pe3ZhciBvLGksZTtmdW5jdGl…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’ because it violates the following Content Security Policy directive: “script-src ‘self’ ‘unsafe-inline’ ‘unsafe-eval’ blob: […list of domains….]”. Note that ‘script-src-elem’ was not explicitly set, so ‘script-src’ is used as a fallback.
