you need to know the code points and eb garamond is not so predictable
(welcome to fonts ...)
\startluacode
fonts.handlers.otf.addfeature {
name = "kernit",
type = "kern",
nocheck = true,
data = {
[0x27E8] = {
["f"] = 300,
["f_l"] = 300,
["f_i"] = 300,
[0xFB01] = 300,
[0xFB02] = 300,
}
}
}

but easier is this (an old mechanism, maybe time for an upgrade with
merged vectors)
\definecharacterspacing [myspacing]
\setupcharacterspacing [myspacing] ["27E8] [right=0.25,alternative=1]
\setupcharacterspacing [myspacing] ["27E9] [left=0.25,alternative=1]
and then
\setcharacterspacing[myspacing]
