Does anyone know how to write off the loss for tax purpose on Russian equity ?

Does anyone know how to write off the loss for tax purpose on Russian equity ? I hold around $70K of Gazprom that I would like to write off as loss for tax purpose to offset some gains for 2023. However, according to TD Ameritrade that seems imposible at the moment. Even if I just want to get rid of it for $0 return. Is this correct? The italic text below is part of the actual message replied to me from TD's representative.

Thanks in advance for the help.

We do have what are called non-marketable orders or nominal orders, which seem similar to what you have presented.
A Nonmarketable Security Transaction is a trade in which TD Ameritrade purchases a security from a client after we have been unable to locate market value for it. These trades net zero dollars for commission and proceeds.
A nominal order, ​​​is a process used to remove a security from an account that is not able to be removed through a normal trade, but is also not eligible to be removed as a non-marketable security​
However, these are both two separate types of trades and would be for eligible positions that do not have any other impactful restrictions, so these may not always be applicable.
In the case of GAZPROM PJSC, shares are restricted due to the Russian Sanctions.
