You can do a replace-first with a regex like

@.*

https://regex101.com/ is a great site for testing your patterns.

Norbert's version:

<do-set-local-variable name="lvSMTP" scope="policy">
<arg-string>
<token-text xml:space="preserve">jhon.doe@sample.mail</token-text>
</arg-string>
</do-set-local-variable>
<do-set-local-variable name="lvCN" scope="policy">
<arg-string>
<token-replace-first regex="@.*" replace-with="">
<token-local-variable name="lvSMTP"/>
</token-replace-first>
</arg-string>
</do-set-local-variable>

Simulation:
test : Applying rule 'lvSMTP'.
test : Action: do-set-local-variable("lvSMTP",scope="policy","jhon.doe@sample.mail").
test : arg-string("jhon.doe@sample.mail")
test : token-text("jhon.doe@sample.mail")
test : Arg Value: "jhon.doe@sample.mail".
test : Action: do-set-local-variable("lvCN",scope="policy",token-replace-first("@.*","",token-local-variable("lvSMTP"))).
test : arg-string(token-replace-first("@.*","",token-local-variable("lvSMTP")))
test : token-replace-first("@.*","",token-local-variable("lvSMTP"))
test : token-replace-first("@.*","",token-local-variable("lvSMTP"))
test : token-local-variable("lvSMTP")
test : Token Value: "jhon.doe@sample.mail".
test : Arg Value: "jhon.doe@sample.mail".
test : Token Value: "jhon.doe".
test : Arg Value: "jhon.doe".

Another simple option: use built-in XPATH function substring-before.

<do-set-local-variable name="lvCN" scope="policy">
<arg-string>
<token-xpath expression="substring-before($lvSMTP,'@')"/>
</arg-string>
</do-set-local-variable>

Simulation:
test : Applying rule 'lvSMTP'.
test : Action: do-set-local-variable("lvSMTP",scope="policy","jhon.doe@sample.mail").
test : arg-string("jhon.doe@sample.mail")
test : token-text("jhon.doe@sample.mail")
test : Arg Value: "jhon.doe@sample.mail".
test : Action: do-set-local-variable("lvCN",scope="policy",token-xpath("substring-before($lvSMTP,'@')")).
test : arg-string(token-xpath("substring-before($lvSMTP,'@')"))
test : token-xpath("substring-before($lvSMTP,'@')")
test : Token Value: "jhon.doe".
test : Arg Value: "jhon.doe".

and many other options available.
