No. Just talking is not and can't be treason. First Amendment.
Nor is proposing secession in and of itself treason. *Armed* secession, through violent insurrection, is treason, but if one state legally put up the option of leaving the Union and all the other states ratified it then there's nothing wrong with being in the party proposing it. (See the independence movements in Alaska, Hawaii, Puerto Rico, etc.)
The Civil War established that states do not have the right to *unilaterally* secede, but we still give Puerto Rico the option to vote on retaining their status in the USA on a regular basis.
